DC to 85 GHz High Performance Components

30 dB Directional Couplers

Pulsar Microwave's CS30 series single directional couplers operate at narrow and wideband frequencies within 500 MHz to 18 GHz. They have a nominal coupling value of 30 dB, with tolerances of +/- 1 to 1.25 dB. These directional couplers are rated at 50 watts maximum input power. These couplers are optimized for best matching and high directivity with flat coupling response. They come standard with SMA or N female connectors.
