SKY77528 Overview
The SKY77528 is a transmit Front-End Module (FEM) designed for quad-band Global System for Mobile munications (GSM), General Packet Radio Service (GPRS), and Enhanced Data Rate for GSM Evolution (EDGE) handsets and modules. The SKY77528 consists of a GSM850/EGSM900 PA block and a DCS1800/PCS1900 PA block, impedance-matching circuitry for 50 Ω inputs and outputs, a multi-function PA control block, lowpass harmonic...
