The SKY77432 is a multi‑mode, multi‑band power amplifier module for 2.5G and 3G handsets, supporting GSM, EGPRS, EDGE and WCDMA.
The SKY77432 module provides true multi‑mode, multi‑band operation for next‑generation handsets. It combines separate high‑band and low‑band GaAs HBT PA blocks with matching circuitry for 100 Ω differential input and 50 Ω single‑ended output, enabling efficient performance in GSM, EGPRS, EDGE and WCDMA modes.
The device is supplied in a 30‑pad, 6 mm × 8 mm × 1.1 mm MCM package and is compatible with a 4.6 V Buck‑Boost DC/DC converter. It supports quad‑band GSM (850/900/1800/1900), EGPRS Class 12 multi‑slot, and 3G bands I, II, III, IV, V, and VIII, with linear and high‑efficiency operating modes controlled via logic‑level pins.
