General Description
The MAX2264/MAX2265/MAX2266 power amplifiers are
designed for operation in IS-98-based CDMA, IS-136-
based TDMA, and PDC cellular telephones operating in
the 900MHz range. When matched for CDMA operation
and biased with margin over the adjacent and alternate
channel specification (-45dBc/-56dBc), the amplifiers
achieve 28dBm output power with 37% efficiency
(MAX2265). At +16dBm output--a very common power
level for CDMA phones--the MAX2265 still has 7% effi-
ciency, yielding excellent overall talk time. At the same
power level, the MAX2264/MAX2266 have an unprece-
dented 12%/17% efficiency, while still obtaining
32%/32% efficiency at maximum output power.
The MAX2264/MAX2265/MAX2266 have internally refer-
enced bias ports that are normally terminated with sim-
ple resistors. The bias ports allow customization of
ACPR margin and gain. They can also be used to
"throttle back" bias current when generating low power
levels. The MAX2264/MAX2265/MAX2266 have excel-
lent gain stability over temperature (0.8dB), so
overdesign of driver stages and excess driver current
are dramatically reduced, further increasing the
phone's talk time. The devices can be operated from
+2.7V to +5V while meeting all ACPR specifications
over the entire temperature range. Nonlinear efficiency
is 48% when matched for linear operation, or 55% when
matched for non-linear-only operation (MAX2265).
The devices are packaged in a 16-pin TSSOP with
exposed pad (EP). For module or direct chip attach
applications, the MAX2264 is also available in die form.

Note 1: Minimum and maximum values are guaranteed by design and characterization, not production tested.
Note 2: P
MAX
is met over this frequency range at the ACPR limit with a single matching network. For optimum performance at other
frequencies, the output matching network must be properly designed. See the Applications Information section. Operation
between 750MHz and 1000MHz is possible but has not been characterized.
Note 3: PAE is specified into a 50
load, while meeting ACPR requirements.
Note 4: Time from logic transition until P
OUT
is within 1dB of its final mean power.
Note 5: Murata isolator as load with 20:1 VSWR any phase angle after isolator.
Note 6: Noise power can be improved by using the circuit in Figures 1, 2, and 3.
Note 7: Harmonics measured on evaluation kit, which provides some harmonic attenuation in addition to the rejection provided by
the IC. The combined suppression is specified.
