40 GHz 2.92 mm Single-Channel Microwave RF Rotary Joint VST-A-RX292F292F-01

P/N: VST-A-RX292F292F-01

– 2.92 mm interface for broadband microwave platforms
– Bridges RF lab setups and 40 GHz fixtures
– Segmented data supports test-plan decisions
– Low torque helps automated moving heads
– Long service life for repeated rotation cycles

Engineering Note
VST-A-RX292F292F-01 is a DC–40 GHz single-channel RF rotary joint for broadband microwave platforms built around a 2.92 mm Female interface. Its role is different from the SMA model’s standard lab coverage and the 2.4 mm / 1.85 mm mmWave options: it gives automated test heads, radar/EW fixtures, and broadband positioners a 40 GHz rotating path with confirmed segmented VSWR, insertion-loss, low-torque, and service-life data for integration planning.

Target Applications

Broadband Microwave Positioner Platforms

2.92 mm rotary interface for systems that need one rotating channel across RF and lower-mmWave test bands.

Radar and EW Fixture Rotation

40 GHz coverage and segmented RF limits support radar/EW fixtures that move during measurement or alignment.

Automated RF Test Heads

Low-torque rotary continuity for moving heads in automated stations where cable twist would affect repeatability.

Broadband Device Characterization Stages

Single-channel microwave path for fixtures that rotate devices or antennas while preserving a 2.92 mm measurement interface.
