Transcription

1 Quad-Band GSM/GPRS Frond End Module with Four TRx Ports Description Features The is a multi-band front-end module (FEM) delivering both the power amplification and antenna switching functions. With the state-of-the-art integration design and advanced GaAs technology, this FEM supports quad-band GSM/GPRS, with matched 50-Ohm RF input and output ports. The FEM also supports UMTS applications through four high linearity TRx ports. The consists of a GaAs HBT power amplifier, a SOI SP6T antenna switch, and a CMOS controller chip. The GaAs HBT power amplifier can work in saturated mode for GMSK signaling. With delicately designed internal low-pass filters, this module provides excellent harmonic suppressions in all operating frequencies. The embedded SP6T switch enables up to 4 TRx ports with low insertion loss and high linearity. The also guarantees robust 8kV high ESD protection for the antenna port. The integrated multi-functional CMOS controller regulates the supply voltage to ramp the output RF power in GSM/GPRS operation, flattens the power variation under battery voltage, ambient temperature, mismatch circumstances, and powers up the SOI switch with internal voltage regulators. Housed in a compact 6.0mmx6.0mmx0.9mm package, the greatly lowers the frond-end complexity of GSM/GPRS solution, facilitates the customer s implementation, and saves board room and cost significantly.
