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.
Features
- Small 25 mm2 package (3.9 x 6.4 x 1.3 mm) - Complete power control - Thermal and load mismatch protection - Harmonic filtering - Input and output matching circuits - Optimal average burst current (ABC) for all power levels - Low powerdown current during receive and standby - GPRS Class 12 compatible - 3.0 to 4.8 V operation - JEDEC moisture sensitivity level (MSL) 1 - RoHS compliant
Applications
- E-GSM 900 and DCS 1800 dual-band cellular handsets - GPRS data terminals
