I am looking for a quick simple way to create a frequency of 200 MHz from 10 MHz. Actually 100, 200, 300 or 400 MHz would all work, but 200 MHz would be my preference. The input will be around 0 to +10 dBm and the output needs to be about +13 dBm. I did think of a x5 x4 frequency multipliers

In my opinion the simplest and cheapest way is to use an ICS 570 it is specked for 180 MHz but we use it repeatedly at 200 MHz. Bert Kehren In a message dated 9/28/2014 6:37:56 A.M. Eastern Daylight Time, p...@phk.freebsd.dk writes: In message

The best solution depends on the situation. Is this to build into the unit? Is it to be permanently applied? Is a DIY solution acceptable, and if so, at what level of complexity? If you happen to have a synthesized VHF generator, just run it from the same reference and set for 200 MHz -
