SKY77318 iPAC PAM for Quad-Band GSM / GPRS
Applications
Quad-Band cellular handsets encompassing - Class 4 GSM850/900 - Class 1 DCS1800/ PCS1900 - Class 12 GPRS multi-slot operation
Description
The SKY77318 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation. The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation. The module consists of separate GSM PA and DCS1800/PCS1900 PA blocks, impedance-matching circuitry for 50 input and output impedances and a Power Amplifier Control (PAC) block with an internal current-sense resistor. The custom BiCMOS integrated circuit provides the internal PAC function and interface
