The four port couplers are excellent for high frequency signal monitoring applications where board space is a premium and quality power detection or injection is required. COTS devices covering C, X and Ku bands offer quick turn solutions in a solder surface mount package with flexible PCB feed line configuration. Both 10dB and 20dB coupling values are available within each frequency band both with a common footprint for maximum flexibility. The devices are designed to provide high directivity, excellent repeatability and stable frequency over the temperature range -55 to +125 ºC. Chip and wire mount devices with the same performance are also available - custom solutions are also available to suit individual size and performance parameters.
