Given the choice of three cascaded doublers with all the intermediate filtering needed, using devices based on a circuit topology even older than the CD4046 (the diode ring or Gilbert cell multiplier

Thanks to all that offered information. I was looking for tomorrows technology and not as one reply indicated something 25 years old !!!!!!!!! from some old fashioned G3O.. living in the dark ages, s

The other method is to use a phase-locked-loop: VCO at output frequency, divided down to the source frequency, phase compared with the source, phase comparator output controls the VCO via a loop filt
Hi Mal, Frequency multiplying is a complete different story than frequency dividing. While the last is done digital, multiplying is a non-linear analog thing. If you want to multiply a signal source
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 capac
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 drivi
