| Preliminary LGA Packaged Phase Shifter for AMPS Base Stations PS088-315 Features Designed for AMPS 881.5 12.5 MHz Band 100 Degree Phase Shift Range 1.5 Degree Phase Deviation 0.3 dB Insertion Loss Deviation 0-12 V Control Voltage Range Specified 33 dBm IP3 Small Footprint LGA Package Description The PS088-315 is a voltage controlled phase shifter designed for use in power amplifier distortion compensation circuits in AMPS band base station applications. Its characteristics are specified in a 25 MHz bandwidth centered at 881.5 MHz. The PS088-315 employs a monolithic quadrature hybrid and a pair of selected silicon varactor diodes to achieve 100 degree phase shift and low insertion loss. The PS088-315 is packaged in the small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
