The IMK Series resistive couplers now come in forward- and reverse-facing directions, with values from 6 to 30 dB. The couplers are rated to 1-W dissipated power at 100°C basaeplate temperature and 5-W through power, depending on values.
The 0.120 x 0.120 x 0.035-in. couplers have an operating frequency of dc to 20 GHz, 1 dB or less insertion loss for nominal values greater than 18 dB. Impedance is 50 Ω, with VSWR at 1:2:1, depending on implementation. (Contact company for pricing and availability.)
