1. [Amps] Looking for shematic to set MRF448 into Class AB (score: 1): Author: "DH5HV" <dh5hv@dh5hv.de>; Date: Wed, 31 May 2006 09:55:42 +0200; Hello. I got a commercial RF-generator for ENI. It has 4 power modules with two ENI21 transistors per module. The ENI21 for sure is a Motorola device and due to the fact that each module should bring; /archives//html/Amps/2006-05/msg00538.html (7,317 bytes)
