PS184-315

Preliminary LGA Packaged Phase Shifter for DCS Base Stations PS184-315 Features ■ Designed for DCS 1837.5 ± 32.5 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 PS184-315 is a voltage controlled phase shifter specifically designed for use in power amplifier distortion compensation circuits centered at 1837.5 MHz in DCS band base stations. Its characteristics are specified in a 70 MHz bandwidth. The PS184-315 employs a monolithic quadrature hybrid and a pair of selected silicon varactor diodes to achieve 100 degree phase shift and low insertion loss. The PS184-315 is packaged in the small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
