- Hi all, First question: when I try to subscribe to the digest, I get an "access forbidden" error message ? But my question relates to swr mismatch protection. My project is a 2 x Blf188XR 1200 watt a

- I should clarify my question; my intent is to do everything practical to protect the FETs - overtemp, overcurrent, and excessive reflected power. The usual location for the reflectometer is after the

- I know that Manfred and others on this list have advanced thermodynamics knowledge - and hope to explore a curiosity of mine regarding high power amplifiers with the current 48 volt big fets. There i

- It's not so much the initial soldering, but future device replacement becomes much more difficult once the large heat spreader is mated to the PC board. Soldering an LDMOS FET onto/into a copper spre

- Please forgive me if my head's been in the sand, but a while back I saw some impressive information about the BLF189XRA. Specifically, increased power level, and significantly better linearity - so g
