100W Tandem Match SWR bridge

Description

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. This bridge very well work with my LDMOS/MOSFET power amplifier controller.

Maximum handled power is 100W.  Coupling – 20dB, that means you will see about 7v DC output for forward wave for 100W RF power
Board size is 49x53mm.
