Device Overview
General Description
The MQH-2655CSP3 is a MMIC 26 - 55 GHz quadrature hybrid. Passive GaAs MMIC technology allows production of smaller constructions that replace larger form factor circuit board constructions. The MQH-2655CSP3 exhibits excellent amplitude balance with broadband quadrature phasing between output ports. Low variation allows for accurate simulations using the provided S4P file taken from measured production units. Tight fabrication tolerances allow for less unit to unit variation than traditional splitter/combiner technologies.
Features
- Designed for Ka/Low V-band applications
- Excellent amplitude and phase balance
- High isolation
- Low insertion loss
