Gil, The power handling capability is limited by the reverse bias voltage applied to the switch, which is about 120 volts under load - so the power limit as implemented in the KPA100 is only about 120 watts.
You would need a bias voltage in the neighborhood of 300 volts to handle 400 watts, and the switching MOSFETs must also be capable of handling that voltage. 73, Don W3FPR > -----Original Message----- > > Anyone have an idea of just how much power the T-R sw. in the > KPA100 would handle over the 100 watts it is handling . 300 -400 watts? > > Thanks Gil K8EAG > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
