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.
