6 dB Directional Couplers from 0.5 to 40 GHz
Pulsar Microwave manufactures the CS06 and CS08 series single directional couplers in nominal values of 6 and 8 dB, respectively. These directional couplers are used in 50-ohm systems for narrow and wideband applications within 500 MHz to 40 GHz. Standard outlines are fitted with SMA or N type female connectors, but Pulsar Microwave can customize upon request.
