Hi.
I am designing a tuned common emitter RF amplifier at about 100 MHz.
How does one match the high collector output impedance to a low load resistance?
I did a simulation and the collector impedance is rather large, about 100 kohm. How do you match this to say a 50 ohm load?
Is it necessary really to match the interstage impedances in a multistage amplifier? Will reflection be a problem between stages (on the same PCB)?
Regards,
RB
