Mini-Circuits has announced the model ZB4PD-232-50W+ coaxial four-way power combiner for applications from 600 to 2300 MHz. The 0-deg.combiner, which can also be used as a power splitter, handles power levels at each of the four ports to 50 W. Insertion loss above the nominal 6-dB combining losses is typically 1.1 dB across the full frequency range. The worst-case isolation between ports is 16 dB across the full frequency range and typically 19 dB. Ideal for cellular, PCS, and DCS applications, model ZB4PD-232-50W+ features typical insertion loss of 0.9 dB from 1800 to 2000 MHz and typical isolation of 28 dB across the same frequency range. The four-way power combiner/divider controls amplitude unbalance to typically 0.05 dB from 600 to 2300 MHz and phase unbalance to typically 0.9 deg. across that same frequency range. The ZB4PD-232-50W+ exhibits good input and output impedance matching, with typical combiner input VSWR of 1.20:1 or less on all four ports and VSWR of 1.10:1 on the summed (combiner output) port. It is supplied with SMA connectors on all five signal ports. The combiner/divider is RoHS compliant and measures 6.00 x 4.50 x 1.39 inches (152.40 x 114.30 x 35.05 mm) not including the SMA connectors. It is designed for operating temperatures from -40 to +85°C and storage temperatures from -55 to +100°C.
It is priced at $199.95 each in quantities of 1 to 9 units.
