Meca Electronics has developed a line of rugged "tee" configuration RF two-and three-way power divider/combiners that are well suited for in-building wireless applications. Models cover the frequency range from 800 MHz to 6 GHz, and all units are rated for maximum input power levels of 20 W. For example, model P3S-1.900V is a three-way power combiner with stainless-steel SMA female connectors that is designed for signals from 800 MHz to 3 GHz. It exhibits typical isolation of 22 dB between ports and typical insertion loss of 0.6 dB (maximum of 0.8 dB) across the full frequency range. Maximum amplitude imbalance is an impressive 0.4 dB while maximum phase imbalance is 6 deg. The typical input and output VSWRs are 1.25:1 and 1.20:1, respectively. Weatherproof versions of all models are also available. For more information on any of these two- and three-way power divider/combiners, visit the Meca Electronics website at:
