PTH 32003
25 W atts, 1.9–2.0 GHz
50-Ohm High-Gain Power Hybrid
Description
The PTH 32003 is a high–gain 50–ohm power hybrid intended for
applications requiring linear amplification and high gain 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. This device may be used as a high–gain 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.
