| 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.
