The H-1-4 SMA is a 180-degree hybrid junction designed for signal splitting, combining, and phase shifting in RF and microwave systems. Operating from 5 MHz to 1 GHz, this component delivers high port isolation and low insertion loss across its frequency range. All four ports terminate in SMA female connectors and accept 50 Ohm source and load impedance, with rated input power handling to 7 W maximum. The device provides approximately 45° phase shift between input and output ports at 300 MHz, varying linearly across the operational band.
