Re: AVANTEK Amplifier Module
I have two of those ‘beasties’ with a ‘welded’ lid but they are 25w., also marked 3.7 – 4.2GHz, no makers name. They both came out of ex-BT 19” rack mounts with 2 huge heatsinks, one for the PSU unit which provided +12v from -28v and the other for the amp – probably ran 24/7/365.
I also have a 15w 6.2GHz unit from the same stable.
I tried a milliwatt or so in from a sig genny and the amp got hot, so did a 25w 3.5GHz rated dummy load..... alas nothing to measure power with, from memory – a least two years ago – it pulled about 8 amps.
I may well get a friend to mill the lid off.
If you, or anyone, have any info I would be grateful.
Best regards to all and looks like another enforced period in the shack coming !

I have a 15W PA 3.7-4.2 GHz which had a (very neat) welded lid. I eventually decided it had to come off which proved to be quicker and easier that I expected on the mill. In fact it had a conventional screwed down lid underneath, so no
need to replace the top.
