.. The maximum power transfer 50% efficiency Po/Pin figure is only valid for a "linear" amplifier termed Class A (current flows through the whole cycle). Other amplifier classes were invented which improved on that 50%. i.e. Class B (push-pull) can approach just shy of 70% (current flows through 50% of cycle), and Class C close to 90% (current flow less than 50% of cycle). Did I misunderstand the problem? What you missed is Richard C. trying to redefine the efficiency of a final amp. :-) -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
