How to search for a RF Frequency Doublers
A frequency doubler is a device whose output is a signal has a frequency of double its input signal. They are non-liner circuits that distort the input signal to generate harmonics of the signal. A band pass filter is then used to select the desired frequency i.e in this case that would be 2 times the input frequency.
When looking for a frequency doubler, the following are the important parameters:
Input Frequency (MHz): This is the input frequency that is to be doubled.
Out Power (dBm): This is the power of the signal whose frequency is double of the input signal.
Conversion Loss (dB): This is the total loss in the signal amplitude of the output signal with double the frequency.
If you are looking for devices that have a different multiplying factor such as 3x, 4x. 6x etc. Look at the RF Frequency Multiplier category.
