Description
The PTH 32003 is a highgain 50ohm power hybrid intended for
applications requiring linear amplification and high gain in the PCS
frequency range. The part is designed to operate with 50ohm source
and load impedances and includes bias circuitry with temperature
compensation. This device may be used as a highgain driver or as a
final output device. The PTH 32003 simplifies system design and saves
space with an overall footprint of 1.21 square inch.
Performance at 1.930 to 1.990 GHz,

- Power Gain = +24 dB Nom.
- Output Power = 25 Watts (P-1dB) Min
- Small Signal Flatness = 0.2 dB Min
Higher gain available with increased bias
voltages
Optimum performance guaranteed with bias
voltages at 8.0 Volts
Exceptional phase linearity and delay
