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
Acrian also supplied a lot of transistors to ENI. The devices might be S200-50 or S250-50. In practice, the difference will not matter to you. Steve _______________________________________________ Am
The transistors may also be related to the MRF428 or the SRF3513 which were the original transistors in the Motorola 300W gain-block that was used almost unchanged in the HF-80. There are lots of des
Hello I found that also which seems to be quiet similar to the things I found in the Motorola application handbook. And that guy has one allready built left and it is designed to bias control 4 direc
