state of the art rf circuit multiplier
I have to realize a circuit of small size which traslates the frequency from 80-110MHz to 240-330MHz. I.e.
I have multiply the frequency by 3.
Which according to you is the best solution to the state of the art.
Hi,
I think you can use an nonlinear circuit(with transistor for example) that distorts the fundamental creating more harmonics and at the output you can use a pass band filter that let only the desired harmonics to pass.Maybe my example is not the best but you can search more of this kind of example.
I have made some filters in practice, but i have made it for cuting the harmonics ,not amplified them.So I think using a filter that cuts the amplified fundamental and also some amplidfied harmonics you can obtain the signal you wish.Good luck
There are several options: as indicated above, you can use any non-linear device like a diode or a transistor and adjust it to generate harmonics, then use a filter to reject all unwanted harmonics.
One interesting device is a parametric tripler, using a step-recovery diode. Such tripler often operates over a narrow frequency band but offers a quite high efficiency.
If you need to multiply the wide band you gave, please see "www.minicircuits.com", they have low-cost commercial triplers for such purpose. There are other manufacturers, too.
