Re: 10W HF Linear PA - QUESTION : Gain? Theory v.s. Practice
|
Not exactly on the topic of power input requirements/limits for the 10W amp . . .
But folks might like to be aware of the following bare PCB kit from QPRBuilder.com if they want to otherwise experiment with the 10W kit.
T/R Switch/LPF Adapter for Power Amplifier.
Looked interesting and I even noodled what would be needed for the pi attenuator to use with the QMX.? Then I decided it was a bit beyond my capabilities, especially for testing for output purity.
Though I suspect that more than a few of the folks I see here on the group might have better skills and interest.

Hello Evan
I'm sure it's written somewhere. Gain varies from build to build and +/-1dB across frequency, and with supply voltage. But generally the required power input to get a solid 10W output is in the range 25-30mW.?

Hans,
The power input range for the 10-watt linear amp is not specified anywhere in the documentation. Based on the 26db gain, my calculations show it is around 30 milliwatts. Can you please confirm the power input limits?
Thank you
