Si4300
Dual-Band Monolithic Power Amplifier System
Description
The Si4300 is a complete, monolithic, high-power, and
high-performance power amplifier system that integrates
all functions and all components between the transmit
portion of the transceiver and antenna switch module
(ASM). The integrated circuit consists of two amplification
paths which supports GSM 900 and DCS 1800. These
amplifiers are General Packet Radio Service (GPRS) class
12 compatible and can be used in GPRS multi-slot
applications. The Si4300 integrates the input and output
matching networks, complete power control, thermal and
load mismatch protection, and many other features and
functions in a single, standard CMOS die on a ceramic
substrate.
