Hello!
I am looking for a design of a directional coupler for HF, 1.8 to 30 MHz
or if possible 50 MHz.
Sofar I tried the original Bruene, that was not referenced to ground,
and a tandem coupler were I "smoked" the toroid after a while.
I tried to work one out in LT spice but I don't trust my spice skills ....
Demands:
Frequency range 1.8 - 30 MHz
Several Kw
Coupling in the range of 30dB or more
High directivity
Dual coupling to do Pwr / SWR measurements.
A "how to design" or a complete design would be nice.
Thank you!
