Description
The PS196-315 is a voltage controlled phase shifter
specifically designed for use in power amplifier distortion
compensation circuits centered at 1960 MHz in PCS band
base stations. Its characteristics are specified in a 60 MHz
bandwidth. The PS196-315 employs a monolithic
quadrature hybrid and a pair of selected silicon varactor
diodes to achieve 100-degree phase shift and low insertion
loss. The PS196-315 is packaged in the small outline LGA
(Land Grid Array) surface mount package with the internal
elements affixed to an organic BT substrate.
