A line of rugged coaxial power dividers from MECA Electronics has been expanded to include two-, four-, eight-, and 16-way dividers capable of handling 30 W continuous-wave (CW) input power from 0.5 to 6.0 GHz. The units are designated models 8xx-2-3.250WWP, where xx = 02, 04, 08, and 16 for the number of output ports. As an example, model 802-2-3.250WWP is a two-way power divider with typical insertion loss of 0.6 dB from 500 MHz to 6 GHz and maximum insertion loss of 1.3 dB across that frequency range. It maintains amplitude balance within 0.3 dB and achieves typical isolation between ports of 22 dB. The typical input VSWR is 1.25:1 and typical output VSWR is 1.20:1. The power divider maintains phase balance within 5 deg. across the frequency range. It measures 4.46 × 2.50 × 0.92 in. and weighs 12 oz.
The power dividers increase correspondingly in size and weight along with the number of ports. The largest member of the group, model 816-2-3.250WWP, is a 16-way power divider with worst-case insertion loss of 4.5 dB and typical insertion loss of 2.5 dB from 500 MHz to 6 GHz. It maintains amplitude balance within 1.2 dB across that frequency range, with worst-case phase imbalance of 15 deg. Typical full-band isolation is 20 dB. The 16-way power divider offers 1.30:1 typical input and output VSWR. It measures 17.00 × 7.96 × 0.92 in. and weighs 10 lbs.
All four power dividers are o-ring sealed and provided in RoHS-compliant aluminum housings with stainless-steel connectors. The power dividers are IP67 weatherproof rated and suited for both indoor and outdoor applications. They are available with a variety of connector types, including Type-N and SMA connectors. All of the power dividers are designed for operating temperatures from -55 to +85°C.
