The circuit has been designed using a single CMOS integrated circuit of model 4069 to produce a frequency that is twice of the input signal by functioning as a frequency doubler. Frequency – a measure ...

If you use a function generator, you may occasionally require a sine-wave output at a higher frequency than the generator can provide. If your function generator also produces a triangle-wave output, ...

It is an age-old problem. You have a 2.5 GHz source and you want it at 5 GHz. You need a frequency doubler. [All Electronics Channel] has an interesting video that talks not only about the theory of ...

Linear Technology has launched a double-balanced mixer that can operate either as an up-converter or down-converter, with a very wide RF frequency range from 2GHz to 14GHz. The LTC5549 is able to ...

[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit is super ...
