Quick Start

The MAX2009/MAX2010 EV kits are fully assembled and
factory tested. Follow the instructions in the Connections
and Setup section for proper device evaluation.

Test Equipment Required

This section lists the recommended test equipment to
verify the operation of the MAX2009/MAX2010. It is
intended as a guide only, and substitutions may be
possible:

· Two DC power supplies capable of delivering +5V

and 20mA of continuous current

· Four adjustable DC power supplies capable of deliv-

ering +5V and 5mA of continuous current

· One high-current power supply capable of biasing a

preamplifier

· One HP 8753D or equivalent network analyzer

· One preamplifier with a gain of 25dB in the 500MHz

to 1100MHz (MAX2010) or 1200MHz to 2500MHz
(MAX2009) frequency range with a minimum output
1dB compression point of 38dBm

· One 6dB attenuator

· One 3dB high-power attenuator

· Two 6dB high-power attenuators

Connections and Setup

Test Set Calibration

1) Set up the test equipment per Figure 1 with the net-

work analyzer output power disabled.

2) Enable the preamplifier.

3) Set the network analyzer to perform a power sweep

from -20dBm to +8dBm at the frequency of interest
and enable the output power. For the best results,
perform the standard network analyzer calibration
with everything except the MAX2009/MAX2010 EV kit.

4) After the calibration, leave the preamplifier connect-

ed to port 1 of the network analyzer.

Testing the Phase Section--Figure 1

1) With the network analyzer's power disabled, con-

nect the output attenuator pad of the preamplifier to
the SMA labeled PHASE_IN (J1).

2) Connect the SMA labeled PHASE_OUT (J2) to the

attenuator pad on port 2 of the network analyzer.

3) With the +5V supply disabled, connect the positive

terminal to the header pin labeled VCC_P. Connect
the ground terminal to a header pin labeled GND.

4) With all adjustable power supplies disabled, set

their voltages to the recommended values in Table
1. Connect these supplies to PB_IN, PD_CS1,
PD_CS2, and PF_S1*. Connect all ground terminals
to the header pins labeled GND.

5) Enable the +5V (VCC_P) power supply first, fol-

lowed by the adjustable supplies.

6) Enable the output power on the network analyzer.

7) With the recommended settings, the AM-PM

response of the phase section should provide a
phase expansion breakpoint of approximately
4dBm and a slope of approximately 1.2°/dB.

8) To power down: First disable the network analyzer,

preamplifier, adjustable supplies, and then the +5V
(VCC_P) supply.

Testing the Gain Section--Figure 2

1) With the network analyzer's output power disabled,

connect the output attenuator pad of the preamplifi-
er to the SMA labeled GAIN_IN (J3).

2) Connect the SMA labeled GAIN_OUT (J4) to the

attenuator pad on port 2 of the network analyzer.

3) With the +5V supply disabled, connect the positive

terminal to the header pin labeled VCC_G. Connect
the ground terminal to a header pin labeled GND.

4) With all adjustable power supplies disabled, set

their voltages to the recommended values in Table
2. Connect these supplies to G_BP, G_FS, and
G_CS. Connect all ground terminals to the header
pins labeled GND.

5) Enable the +5V (VCC_G) power supply first, fol-

lowed by the adjustable supplies.

6) Enable the output power on the network analyzer.

7) With the recommended settings, the AM-AM

response of the gain section should provide a gain
expansion breakpoint of approximately 5dBm and a
slope of approximately 0.5dB/dB.

8) To power down: First disable the network analyzer,

preamplifier, adjustable supplies, and then the +5V
(VCC_G) supply.

Detailed Description

The following sections describe the tuning methodology
best implemented with a class A amplifier. Other classes
of operation may require significantly different settings.

Supply Decoupling Capacitors

Capacitors C4 and C5 are 0.01µF (±10%) and are used
for minimizing low-frequency noise on the supply.

External Matching Components

The MAX2009 external matching networks at the input
and output of the phase and gain sections consist of
C1, C11, C10, C12, C9, C8, C6, C7, along with some
high-impedance transmission lines. The MAX2010
matching consists of C1, C11, L1, L2, C10, C12, C9, C8,
C6, and C7.

Phase-Tuning Section

Varactors VR1 and VR2 provide fine tuning of the
phase-expansion slope. Resistors R1 and R2 provide a
high-impedance method to inject control voltage on the
varactors. Capacitors C2 and C3 are coupling capaci-
tors that also offset the series parasitic inductance of
the chip and PC board. If phase-slope fine tuning is not
required in the user's application, then only C2 and C3
to ground are necessary.

Gain and Phase Controls

The MAX2009/MAX2010 controls can provide real-time
software-controlled distortion corrections as well as set-
and-forget tuning by setting the expansion starting
point (breakpoint) and the rate of expansion (slope).
The gain and phase breakpoints are adjustable over a
20dB input power range. The phase expansion slope is
variable from 0.3°/dB to 2.0°/dB and can be adjusted
for a maximum of 24° of phase expansion. The gain
expansion slope is variable from 0.1dB/dB to 0.6dB/dB
and can be adjusted for a maximum of 7dB gain
expansion.

Phase-Expansion Breakpoint

The PB_IN input voltage range of 0V to V

corre-

sponds to a breakpoint input power range of 3.7dBm to
23dBm. In order to achieve optimal performance, the
phase-expansion breakpoint of the MAX2009/
MAX2010 must be set to equal the phase compression
point of the PA.

Control pin PBRAW should be shorted to the PBEXP
output pin for most applications. Driving PBRAW direct-
ly allows for additional control such as obtaining phase
compression for some and/or all the input power
sweep. Resistor R3 allows the option of driving PBRAW
with a low-impedance voltage, which overrides the
PBEXP output voltage.

Phase-Expansion Slope

The phase-expansion slope of the MAX2009/MAX2010 is
controlled by the PF_S1, PF_S2, PD_CS1, and PD_CS2
pins. Most applications require PF_S1 and PF_S2 to be
driven identically, and therefore they are shorted on layer
4 of the PC board. The phase-expansion slope of the
MAX2009/MAX2010 must also be adjusted to equal the
opposite slope of the PA's phase-compression curve.

Gain-Expansion Breakpoint

The G_BP input voltage range of 0.5V to 5.0V
corresponds to a breakpoint input power range of -3dBm
to 23dBm. In order to achieve the optimal performance,
the gain-expansion breakpoint of the MAX2009/
MAX2010 must be set to equal the gain-
compression point of the PA. The G_BP control has a
minimal effect on the small-signal gain when operated
from 0.5V to 5.0V.

Gain-Expansion Slope

Both G_CS and G_FS pins have an input voltage range
of 0V to V

, corresponding to a slope of approximately

0.1dB/dB to 0.6dB/dB. The slope is set to maximum
when V

GCS

= 0V and V

GFS

= +5V, and the slope is at

its minimum when V

GCS

= +5V and V

GFS

= 0V. In addi-

tion to properly setting the breakpoint, the gain-expan-
sion slope of the MAX2009/MAX2010 must also be
adjusted in order to compensate for the PA's gain com-
pression. The slope should be set using the following
equation:

MAX20XX_SLOPE =

where:

MAX20XX_SLOPE = MAX2009/MAX2010 gain section's
slope in dB/dB.

PA_SLOPE = PA's gain slope in dB/dB, a negative
number for compressive behavior.

Unlike with the G_BP pin, modifying the gain-expansion
slope bias on the G_CS pin causes a change in the
part's insertion loss and noise figure. For example, a
smaller slope caused by G_CS results in a better inser-
tion loss and lower noise figure.

Modifying the EV Kit

The external varactors on the EV kit can be replaced with
fixed capacitors if dynamic tuning of the fine phase-
expansion slope through PF_S1 and PF_S2 is not
required. A closely matched minimum effective capaci-
tance of 2pF to 6pF must be presented at these pins.

Component pads for external filtering components are
included for pins PB_IN, PB_RAW, G_BP, G_CS, and
G_FS.

Pins PF_S1 and PF_S2 are shorted together on the EV
kit. If independent control is required, disconnect the
trace connecting these two pins on the bottom side of
the PC board (pins 19 and 20 of J5).

Layout Considerations

The MAX2009/MAX2010 EV kits can serve as guides to
board layout. Pay close attention to thermal design and

placement of components on the PC board. The pack-
age's exposed paddle (EP) dissipates heat from the
device and provides a low-impedance electrical con-
nection. The EP must be solder attached to a PC board
ground pad. This ground pad should be connected to
the lower ground plane using multiple ground vias. The
MAX2009/MAX2010 PC boards use a 3 x 3 grid of
0.012in diameter plated through holes. The MAX2009
layout uses high-impedance lines on the input and out-
put paths of the gain section to aid in matching. In an
actual application, matching capacitors C7, C9, C11,
and C12 could be replaced with a microstrip equivalent
solution to reduce component count. In order to pro-
vide increased tuning range, the ground plane under
the varactor control section has been removed. The
MAX2009/MAX2010 EV kits are constructed on FR4
with the top dielectric thickness of 0.015in.
