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.
The Maxim MAX2264, MAX2265 and MAX2266 are single‑supply, cellular‑band linear power amplifiers designed for CDMA, TDMA and PDC phones operating in the 900 MHz range. They operate from +2.7 V to +5 V and provide up to 28 dBm output power with high efficiency.
The datasheet includes absolute maximum ratings, DC and AC electrical characteristics, typical operating curves, and application notes such as bias‑current adjustment and shutdown mode operation. Performance graphs illustrate power‑added efficiency, gain versus temperature, and adjacent‑channel power ratios.
