The MAX2267/MAX2268/MAX2269 power amplifiers are
optimized for IS-98-based CDMA and PDC cellular tele-
phones operating in the Japanese cellular-frequency
band. When matched for CDMA operation, the ampli-
fiers achieve 27dBm output power with 35% efficiency
(MAX2268), with margin over the adjacent and alternate
channel specification. At a +17dBm output—a very
common power level for CDMA phones—the MAX2268
still has 7% efficiency, yielding excellent overall talk
time. At the same power level, the MAX2267/MAX2269
have an unprecedented 12%/17% efficiency, while still
obtaining 28%/29% efficiency at maximum output
power.
The MAX2267/MAX2268/MAX2269 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 MAX2267/MAX2268/MAX2269 have excel-
lent gain stability over temperature (±0.8dB), so over-
design 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
+4.5V while meeting all ACPR specifications over the
entire temperature range.
The devices are packaged in a 16-pin TSSOP with
exposed paddle (EP). For module or direct chip attach
applications, the MAX2267 is also available in die form.
