Would be helpful (essential!) to show how you have it connected!

very good. I wish that you showed how the test equipment was attached to the amp.

Hello, then what is the input and output impedance of the BLF188XR at 15 Mhz is it possible to know it. Thank you

Hi, so the VNA is attached to the output transformer secondary via a 1/4 length 50 ohm stub. Do I have that right? What's the point of the stub? I mean, what difference would it make if you connected the VNA directly?

I agree since the frequency range is wide, you would need a bunch of 1/4 stubs for all the frequencies. Connecting directly should eliminate the effects of any resonant coax.

"SWRs". Nope, SWR is not plural. All you US guys seem to do it: VSWR: Voltage Standing Wave Ratio. Not "Ratios" ! Hope it helps!

Thanks, loving my purchased kit. Off topic purchasing an IC-705 and looking for 100 watt HF amplifier kit for portable use it can be a little big, any recommendations? Thanks.

I'm happy to hear that you like my LDMOS Board! I know someone who purchased this board on eBay for less then $100 and is very satisfied with it. www.ebay.com/itm/283603540399?hash=item42081699af:g:AfAAAOSw7L1dbz7R

please use a tripod. watching at 2x speed gives a headache due to video shaking.
