This is high quality 1-55MHz SWR bridge. You can use it as part of HF power amplifier or separate SWR/Power meter. This bridge has good directivity in 1-55MHz band. You can see above the grath for directivity. Negative ALC output available. Maximum handled power is 1.5KW. This bridge very well work with my LDMOS/MOSFET power amplifier controller.
Maximum handled power is 1500W. RF coupling factor is -29 dB, that means you will see about 8v DC output for forward wave for 1500W RF power. Board size is 49x76mm.
