High Performance Hybrid Couplers for Wideband Applications to 40 GHz

August 10, 2021

To support wideband applications, Pasternack has expanded its line of RF hybrid couplers, adding 21 models and extending frequency coverage to 40 GHz. These coaxial designs, with SMA or 2.92 mm connectors, provide an even split with 90- or 180-degree phase shift and flat phase and amplitude balance across the frequency range. They have low insertion loss, good return loss and high isolation between ports, with power handling capability up to 100 W CW.

As one example of the extended family, the PE2CP1150 is a 3 dB coupler covering 2 to 40 GHz and providing 90 degree phase shift between the two output ports, with 10 dB minimum isolation between ports. The typical phase balance is ±8 degrees, ±10 degrees maximum, and the amplitude balance is ±0.8 dB typical, ±1.2 dB maximum. Typical insertion loss is 1.3 dB, 2.5 dB maximum. Input power handling is 20 W CW and 200 W peak. For best performance at the upper end of the frequency range, the coupler has 2.92 mm female connectors on all ports. The operating temperature range is –45°C to +85°C.

The family includes couplers for narrower bandwidth applications, such as the PE2CP1161, a 3 dB coupler with a 180-degree split, covering 26.5 to 40 GHz with 15 dB minimum isolation and 2.5 dB maximum insertion loss. Maximum phase and amplitude balance are ±6 degrees and ±1 dB, respectively. Input power handling is 20 W CW and 300 W peak, and the coupler has 2.92 mm female connectors on all four ports.

As with Pasternack’s broad line of RF, microwave and mmWave components, these hybrid couplers are in stock and available for immediate shipping. No minimum order quantity is required.
