Description
The PS094-315 is a voltage controlled phase shifter
specifically designed for use in power amplifier distortion
compensation circuits centered at 942.5 MHz in GSM
band base stations. Its characteristics are specified in a
35 MHz bandwidth. The PS094-315 employs a monolithic
quadrature hybrid and a pair of selected silicon varactor
diodes to achieve 100 degree phase shift and low insertion
loss. The PS094-315 is packaged in the small outline LGA
(Land Grid Array) surface mount package with the internal
elements affixed to an organic BT substrate.
