Resistive Couplers Span DC To 15 GHz

The IMK series of resistive couplers from International Manufacturing Services, Inc. (IMS) is available for applications from DC to 15 GHz. The resistive couplers can be specified with values of 6 to 30 dB with less than 1 dB insertion loss for coupling values greater than 18 dB. The VSWR is typically 1.2:1 while the typical power-handling capability is 1 W. Fabricated with thick film on alumina substrates, the couplers measure 0.120 x 0.120 x 0.035 in. or less. Samples of the IMK series resistive coupler are available by visiting the company's web site.
