PTH 32003 25 Watts, 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.
