Directional RF Couplers Take Up Little Space

Designed to monitor incident or reflected power, the company's directional RF couplers measure 0.65" x 0.5" x 0.38" excluding connectors and weigh 0.1 oz. For measuring RF energy, they operate over a frequency range of 10 MHz to 3 GHz with a coupling value of 14.2 ± 0.75 dB. They are available in a variety of configurations and connector options of SMA or SMB and through-hole mounting. With a maximum input power of 3W, maximum insertion loss is 1 dB from 10 MHz to 1 GHz, 1.5 dB from 1 GHz to 2 GHz, and 2 dB from 2 GHz to 3 GHz. Minimum return loss figures are 18 dB from 10 MHz to 1 GHz, 15 dB from 1 GHz to 2 GHz, and 14 dB from 2 GHz to 3 GHz. Minimum directivity specs are 14 dB from 10 MHz to 1 GHz and 11 dB from 1 GHz to 3 GHz. MICROPHASE CORP., Norwalk, CT. (203) 866-8000.
