Microwave loop couplers

13 April 2011 Telecoms, Datacoms, Wireless, IoT

New from Link Microtek’s engineering division is a range of microwave loop couplers that offer higher directivity values than equivalent cross-guide couplers and are also significantly smaller. Suitable for monitoring microwave power levels in applications as diverse as X-ray machines and radar antennas, the AM-LC series of loop couplers cover frequencies from 2,6 to 40,0 GHz and can achieve directivities as high as 40 dB, enabling highly accurate measurements to be made.

The devices range in length from 25 mm to 200 mm for standard waveguide sizes WR28 to WR284, and all models can be specified with coupling values of 30, 40 or 50 dB and a choice of SMA, N-type or TNC connectors. The loop couplers feature low insertion losses and low VSWR values, as well as the capability to handle full waveguide power. They are fabricated from lightweight Alochromed aluminium with a black satin paint finish and can also be supplied in brass or other materials to special order.
