说明

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% efficiency, yielding excellent overall talk time. At the same power level, the MAX2264/MAX2266 have an unprecedented 12% /17% efficiency, while still obtaining 32% /32% efficiency at maximum output power.

The MAX2264/MAX2265/MAX2266 have internally referenced bias ports that are normally terminated with simple 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 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 +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.
