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.
