This is a W6PQL based 150 watt linear amplifier with 2 stages of driver amplifiers , primarily intended for DATV but will be ok for all modes.
It has high gain, needing only 20mW for full power.?
55dB gain
28 volt 14 amps max.
I am asking ?400 + postage (?30 with full insurance to UK)
don't reply here because I don't monitor very often - email me at thebigclunk@...

I have a few of these pallets with?2x BLF8G22LS-160BV?available as received unmodified at ?60.00 + postage
if you want one/some then email me?thebigclunk@...
I have decided to go back to using the pallets with three of the same devices as they give me less problems
I will supply some power connector pins with them.

Description:
My latest 2.4GHz amplifier project using a pallet from bisonelectronics-sp2iyr on Ebay and modified to give 75-80W from a 28 volt supply at 15 amps max and a max drive level of 250mW. P1dB is around 50-60W at about 31dB gain (conversion details will be in the next issue of CQ-TV and I will post the article as a file on this site) Heatsink is PS200/250 from GD Rectifiers Box is Hammond 1550J (275x175x67) I used the original semi rigid cables as I had some although I convert most pallets to take SMA so you would still need to make up semi rigid RG-402 cables so as not to put too much load on the SMA sockets.
