Q-Band Waveguide Cassegrain Antenna

This item is oversized and will require special packaging. Pricing for a custom crate will be quoted separately.

SAY-3735135302-22-S1-DP-WR is a dual polarized Cassegrain Weather Resistant antenna assembly for new space satellite communication system ground station applications. The antenna assembly offers a nominal gain of 53 dBi and a half power beamwidth of 0.2 degrees. The assembly features an integrated orthomode transducer (OMT) that provides high port isolation and cross-polarization cancellation between the transmitting and receiving ports. The H and V port of the OMT has an integrated band-pass filter with pass-band frequency ranges 46 to 51 GHz for TX and 37 to 42 GHz for RX respectively. The filters offer 40 dB typical rejection between the TX and RX frequencies. The main reflector is fabricated with fiber glass to offer a light weight and rugged mechanical structure. The corrugated horn is used to provide the best feed efficiency and the most uniform illumination. The antenna also features a linear to circular polarizer to transform linear waveforms to circularly polarized waveforms. The antenna can also support linear waveforms which are offered under a different model number. The TX and RX ports are WR-22 waveguide bulkheads with UG-383/U anti-cocking grooved flanges and removable O-rings.
