PS214-315

Preliminary LGA Packaged Phase Shifter for UMTS Base Stations PS214-315 Features ■ Designed for UMTS 2140 ± 30 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 PS214-315 is a voltage controlled phase shifter specifically designed for use in power amplifier distortion compensation circuits centered at 2140 MHz in UMTS band base stations. Its characteristics are specified in a 60 MHz bandwidth. The PS214-315 employs a monolithic quadrature hybrid and a pair of selected silicon varactor diodes to achieve 100 degree phase shift and low insertion loss. The PS214-315 is packaged in the small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
