You could use a JFET in self-biased mode. I would use a 100k series resistor
to feed the gate of the JFET; these devices typically have an input C of
around 8pF. You don't want to end up detuning your mixer circuit. The 100k
resistor should provide the desired isolation.

I have an IC-290A to which I'd like to add a 10.7mhz IF output. I need
bandwidth of about 1mhz and it appears the best place to get this
signal is off of the mixer output pin. How should this output be
coupled to the mixer output? Is any isolation necessary? What should
I know before I attempt this? (I can solder well, etc...)
