Description
The PTH 31002 is a 50–ohm power hybrid intended for applications
requiring linear power amplification in the PCS frequency range. The
part is designed to operate with 50–ohm source and load impedances
and includes bias circuitry with temperature compensation. The design
is intended to simplify system design and save space with an overall
size of less than one square inch.
Guaranteed Performance at 1.93 to 1.99
