SKYA22000数据手册Skyworks中文资料规格书

描述 Description

The SKYA22000 power amplifier module (PAM) is designed for 2G quad-band telematics boxes supporting fixed gain Gaussian Minimum-Shift Keying (GMSK) and fixed gain linear Enhanced Data for GSM Evolution (EDGE) modulation in the GSM850/900, DCS1800 and PCS1900 bands. Class12 General Packet Radio Service (GPRS) multi-slot operation is also supported.

The compact 3.0 mm x 3.5 mm x 0.8 mm module consists of GSM850/900 and DCS1800/PCS1900 power amplifier blocks, 50-ohm input and output matching circuitry, and a multi-function power amplifier control (MFC) block. The custom silicon CMOS MFC provides PA bias and product identification read-back capability and is fully programmable through the RF Front-End Mobile Industry Processor Interface (RFFE MIPI).

The heterojunction bipolar transistor (HBT) power amplifier blocks are fabricated onto a single lnGaP die; one supports the GSM850/900 bands and the other supports the DCS1800/PCS1900 bands. Both PA blocks share two common power supply pads. The InGaP die, silicon die, and the passive components are mounted on a multi-layer laminate substrate. The entire assembly is encapsulated with plastic over mold.
