Hi,
I have a Xiegu XPA20 amplifier to “look at” from a surplus sale, but no info. (20W out for 5W in, I found a reference to it and a basic spec on the Russian Yaesu website :o)
It powers up, and I can scroll through the LPF settings - I haven’t tried putting any RF into it yet, as I’d like to understand a bit more about it first.
It seems to be quite a rare beast, and several years old - so, has anyone got one? Especially, a copy of the manual would be nice!
Thanks,
Adrian
Hi Adrian - here you go:
XIEGU XPA20 6 Band 20 Watt Power Amplifier 1 User`s manual | Manualzz
An interesting two lines in the manual:
System running in SSB Mode: peaks of around 45 W into a 50 ohm dummy load across all bands.
System running in CW Mode: 20 W
That suggests to me that the amplifier gives 20W RMS output or 45W PEP.

Thanks Ed - that’s great!
I noticed in the brief spec that I found, it draws up to 7.5 Amps - which sounds quite high (90W at 12V) for a 20W amplifier…
The heat sink is quite small, perhaps that’s why they limit the power on CW, and maybe don’t use a speech processor on SSB :o)
Anyway, I’ll have a play with it.
