BASINGSTOKE, England, 27 July 2015. Link Microtek Ltd UK in Basingstoke, England, is introducing the AM28CORJD RF and microwave miniature dual-channel rotary joint designed to save space in antennas for military and commercial Ka-band satellite-on-the-move communications.
With its high-power transmit channel implemented in a right-angle WR28 waveguide on the fixed (input) side and a female K-type coaxial connector on the rotating (output) side, the AM28CORJD rotary joint measures 31.75 by 74.68 millimeters, excluding the 50-millimeter-diameter UBR320 standard bulkhead flange.
The central transmit channel covers Ka-band frequencies from 29 to 31 GHz and delivers microwave performance, with a maximum power rating of 40 Watts continuous wave, a typical insertion loss of 0.6dB and a maximum voltage standing wave ratio (VSWR) of 1.25:1.
The L-band receive channel uses two female SMA coaxial connectors and operates over DC to 2.15 GHz. It offers a microwave power rating of 1 Watt continuous wave, a maximum DC current rating of 0.5 amps, an insertion loss of 0.25dB, and a typical VSWR of 1.5:1.
