The P751-412 from L3Harris Narda-ATM is a Mechanical Phase Shifter that operates from 13 to 15 GHz. It has a 0 to 360-degree phase range and an insertion loss of 0.25 dB. The phase shifter can handle power up to 50 Watts of power and is available in a module with Female SMA Coaxial-Connectors.
This phase shifter uses high unloaded Q low loss cavities, which limits its bandwidth but at the same time results in very low loss when compared to a standard coaxial phase shifter. It is ideally suited for applications requiring low loss and loss variations.
