High Power Single and Dual Directional Couplers
Pulsar Microwave manufactures a line of single and dual directional couplers specifically designed for high power operation. There are various narrow and broadband designs from 0.1 MHz to 10 GHz. These directional couplers come in standard values of 30, 35, 40 and 50 dB with coupling tolerance of +/- 1 dB. The high power directional couplers have low insertion loss. Coupling flatness is maintained at +/- 1 dB or less among models. Most units hold a mainline VSWR of 1.2:1 or better throughout the operating frequency range. Pulsar Microwave has designs up to 2.5 kW input power. Typical directivity is 20 dB or more. Standard outlines are available with SMA or N type female connectors. For higher power ratings, typically the mainline will use N connectors with SMA on the coupled ports.
