Model 4010265SQ is a 180º hybrid coupler specifically designed for space applications operating over the ultra-broadband frequency range of 1.0 to 26.5 GHz. It is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. Covering the microwave frequency bands from L- through K-band, this unit offers superior performance ratings, including coupling of 3 dB, amplitude imbalance of +/-1.0 dB (1 to 20 GHz) and +/-1.5 dB (20 to 26.5 GHz), phase imbalance of +/-16º, isolation of >15 dB, maximum VSWR of 1.8 (1 to 20 GHz) and 1.95 (20 to 26.5 GHz), and insertion loss of 3.0 dB (1 to 20 GHz) and 3.6 dB (20 to 26.5 GHz). Input power rating is 20W average and 3kW peak. The hybrid coupler comes with four industry-standard SMA Female connectors. Its compact package measures just 4.04 x 1.35 x 0.52” and weighs only 4.6 ounces.
