The HP/Agilent 11636B is a precision power divider that splits signals from DC to 26.5 GHz with symmetrical 6 dB division across three 3.5 mm connectors. It delivers minimal insertion loss (6.0 dB nominal + 0.04 dB/GHz) and excellent port impedance matching, making it ideal for wideband comparison measurements, transmission line fault testing, and power combining applications. The device exhibits tight amplitude tracking of 0.25 dB at 18 GHz and phase tracking of ±2 degrees typical between output arms, with maximum SWR of 1.29 across its operating range. Rated for 1 W CW operation into 50 Ohm loads, the 11636B requires no field maintenance and weighs 170 g.
