DC to 85 GHz High Performance Components

Directional Couplers, 0.01-2000 MHz

Pulsar Microwave's low frequency directional couplers operate within the frequency range of 10 kHz to 2 GHz. They're available in either surface mount or connectorized designs. SMA female connectors are standard, but BNC, TNC, F, N, jack or plug are available upon request.

Most of these directional couplers have a flatness of +/- 0.25 dB and directivity of 20 dB or better within the operating band. VSWR of 1.3:1 or better maintained on all ports for most models. Maximum power handling is between 1 and 3 watts depending on model.
