Si4300T
Tri-Band Monolithic Power Amplifier System
Description
The Si4300T 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, DCS 1800, and
PCS 1900. These amplifiers are General Packet Radio
Service (GPRS) class 12 compatible and can be used in
GPRS multi-slot applications. The Si4300T 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.
