Wanted, G3XDY filter/Reflectometer or a QRO directional coupler
Hi Nick, for what band do you need a coupler and what is the legal limit ? Normally the resistor is the limiting factor or (if you speak of POWER) the SMA or N conector. 73, Rainer Am 23.06.2022 um 22

Kuhne MKU 23 G4 and MKU PA 23cm
Hi John, the best would be to reduce the output to abt. 20dBm (you can set it via the IF drive or use a 10dB attenuator) and get a RA181213G from Mitsubishi to drive the 23cm PA to 250W max. maintaini

Kuhne MKU 23 G4 and MKU PA 23cm
Hi John, the 23cm PA can NOT be used with MKU 23 G4 as this transverter is for 13cm / 2.3GHz !!! You need a MKU 13 G3 !!! 73, Rainer Am 29.04.2022 um 13:16 schrieb lostbeach via groups.io:

Radiall Relay Using Outside Spec
Hi Marc, the relay has a minimum isolation of 80dB @ 3GHz so it will be very usable at 3,4GHz. Also the Insertion Loss shpuld be no problem. Try it and you will be satisfied ! 73, Rainer Am 18.02.2021
