Linear Power Amplifiers  
General Description  
Features  
ꢀ Low Average CDMA Current Consumption in  
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.

Circuitry Needed  
ꢀ Supply Current and ACPR Margin Dynamically  
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 (±±.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.
