Use three  push-push doublers in series.

minicircuits do one, but the LF spec is 50KHz, so you might have
to build a discrete one for the first stage (center-tapped transformer,
two-diodes and a capacitor)

Hello All
There are numerious chips available for dividing frequency but what is
available for multiplying, eg.
I have a W & G freq generator  200 hz - 20 khz and want to use it for
136 khz as a driving tx source. Is there a chip device that multiplies
this up to the desired freq.
say x 8 1600 hz - 160 khz.
I am trying to avoid the convential method with descrete components,
another approach would be to mix/hetrodyne it to the desired freq with
an appropriate xtal osc cct.
All advice appreciated.
