Exactly that was I was looking for - a fast "bus" switch with low 
on-resistance. Hopefully easier to find than some Plessey ICs..
I will try this in an image-cancelling mixer for my next LF exciter, 
maybe also in a new receiver.
So far, a cheap 4.4336119 MHz crystal, a CMOS 4060 oscillator/divider, 
and an EXOR gate are all it takes to generate an 138.5 kHz quadrature 
signal to the two mixers...
