SI4300T

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. 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, DCS 1800, and PCS 1900 dual-band cellular handsets - GPRS data terminals VBAT APC Low Pass Filter Power Control Si4300T RFIL Limiter PA Matching Network Harmonic Filter RFOL GND Matching Network Limiter PA RFOH Harmonic Filter RFIH TLIMIT PAEN VDD SHUTD BSEL Monitor, Control, and I/O Interface Temperature and Voltage Sensor...
