Model 264030 is a broadband 30 dB directional coupler that operates over a frequency range of 26.5 to 40 GHz in a compact and lightweight design. The coupler is well suited for wireless designs as well as many test and measurement applications within K-band. It is also designed for systems applications in which external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements are required. Nominal coupling with respect to output is 30 dB ±1 dB and frequency sensitivity is ±0.5 dB. Insertion loss including coupled power is 1.3 dB, directivity is greater than 12 dB, and maximum VSWR is 1.7:1. It can handle a maximum input power of 20 W average and 3 kW peak.
