A 4-way RF power divider/combiner operates over 2.0 to 4.0 GHz with SMA-female connectors and 50 ohm nominal impedance. The divider is rated for 20 W average input power and has all output ports in phase. Electrical performance includes 0.7 dB maximum insertion loss above the theoretical 6.02 dB split, 0.2 dB maximum amplitude balance, 4 degree maximum phase balance, and 20 dB minimum isolation. The mechanical construction uses brass nickel-plated connectors, beryllium-copper gold-plated pins, an aluminum yellow-iridite housing, and Teflon virgin electrical-grade insulators. The operating temperature range is -55°C to +85°C.
