Tahoe RF Semiconductor, Inc. 
Part Number : TRFS-551
Overview :
The TRFS-551 PA Driver has dual power amplifier drivers for multi-band wireless communication applications operating at 900MHz and 1.9GHz. The two amplifiers are 2-stage bipolar amplifiers with 50Ω single-ended outputs, and a dedicated bias utilizing an external current setting resistor. The amplifier can be set to operate in one of four linearity modes by programming the bias current. This helps to conserve chip power consumption under average power conditions as well as meet the peak power requirement. This core circuitry can be easily integrated with other circuits as well as packaged individually into a leadless chip carrier.
Features : - Multi-band power amplifier drivers at 800-950MHz and 1.75-1.98GHz
- Each amplifier is a 2-stage bipolar single ended circuit
- Four linearity modes with OIP3=31dBm at max. current of 60mA
- Linear gain of 20dB for both
