30-watts dissipating as heat in the front end of the amp. The 3dB pad does improve return loss into the amp input by the same amount. But, the effective gain factor of the amp is then reduced by 3dB.>>>
A 3dB pad gives 6 dB return loss. For example if load SWR is 2:1 (5.5dB RL) and we add a 3 dB pad, return loss is 9.5 dB (1.4:1 SWR). A 3 dB 50 ohm pad with an open circuited output looks like 150 ohms. You can make a 3:1 SWR test fixture by opening and shorting the output. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
