Matt, You'll be very lucky to find data for an old exotic beast like that. It looks like a step recovery diode feeding a big honkin' bandpass filter. Expect the output power to be around a milliwatt, give or take a factor of 10. Keep the 100 MHz input power under half a watt for starters, to keep from burning it out too soon. That's the typical max input rating for the step recovery diode that they likely used. Start at zero, turn up the input power slowly and watch the output power with a spectrum analyzer or power meter (I assume that all that filtering inside it will keep the fundamental out). When it starts to work, the 7.6 GHz output power should go up quickly with a smaller increase in input power. The trouble is, the ideal operating power is probably about 4 dB less than the power required to blow out the diode. Good luck with it! --David Forbes _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
