MAX2267/MAX2268/MAX2269
The MAX2267/MAX2268/MAX2269 power amplifiers are optimized for IS-98-based CDMA and PDC cellular telephones operating in the Japanese cellular-frequency band. When matched for CDMA operation, the amplifiers achieve 27dBm output power with 35% efficiency (MAX2268), with margin over the adjacent and alternate c h a n n e l 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 o b t a i n i n g 28%/29% efficiency at maximum output power. The MAX2267/MAX2268/MAX2269 have internally referenced bias ports that are normally terminated with simp l e resistors. The bias ports allow customization of A C P R margin and gain. They can also be used to "throttle back" bias current when generating low power levels. The MAX2267/MAX2268/MAX2269 have excellent 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 +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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
