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.
