Description
The SKY77360-12 power amplifier module (PAM) is designed
for 2G quad-band cellular handsets supporting fixed gain
Gaussian Minimum-Shift Keying (GMSK), fixed gain linear
Enhanced Data for GSM Evolution (EDGE) modulation in the
GSM850/900 and DCS1800/PCS1900 bands, and TD-SCDMA
modulation in Bands 34 and 39. Class12 General Packet Radio
Service (GPRS) multi-slot operation is also supported.
The compact 3.0 mm x 3.0 mm x 0.67 mm (Max) module
consists of GSM850/900 and DCS1800/PCS1900/B34/B39
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/ B34/B39 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.
