A fundamental building block of microwave systems, power splitters and combiners are always in demand, and even small improvements in performance will help system performance, such as reducing noise figure, increasing dynamic range or improving the amplitude and phase matching in multichannel systems.

The Mini-Circuits’ ZN4PD-02183+ is a 50 Omega;, four-way, in-phase splitter/combiner that covers 2 to 18 GHz. Added insertion loss, above the theoretical 6 dB split, is typically 1.0 dB, 1.6 dB maximum. The typical channel-to-channel amplitude and phase imbalance are 0.3 dB and 3.5 degrees, respectively, and isolation between any two channels is typically 20 dB, 16 dB minimum. Typical VSWR is 1.45:1 at the sum port and 1.35:1 at ports 1 to 4. Used as a splitter, the maximum input power is 30 W, and each of the four ports can carry up to 150 mA DC current (600 mA at the sum port). The splitter/combiner is fabricated in a 2.5 in x 4 in x 0.38 in aluminum alloy housing, with SMA female connectors. It has an extended operating temperature range from −55°C to +100°C and is RoHS compliant.

The broad frequency coverage of the ZN4PD-02183+ supports the requirements of electronic warfare and test and measurement applications and can simplify system architectures. The channel-to-channel amplitude/phase matching and isolation help maintain signal integrity in multichannel systems.

The ZN4PD-02183+ is in stock and available for shipment.
