All,
I have an older transistor based transceiver. I have separated the
circuit and substituted an external signal generator in place of the
internal circuit. The circuit drives a mixer, by varying the amplitude
the mixer performs better with about a 4x increase in drive.
My question is: what is the best way to increase the output of an
amplifier stage?
Is it as simple choosing a transistor with a higher beta?
There are two nearly identical stages. Both are NPN, the collector bias
is a resistor - inductor in series and the emitter circuit is a
capacitor - resistor in parallel. Would reducing the resistor values
increase gain?
If this question is too general - where is a good source for reading
about stage gain variables?
Thanks - Dan
