Frequency Doubler

If you are working at frequencies of the order of 850 MHz to 4 GHz and find that a frequency multiplier is required, the HMC 187, HMC 188 and HMC 189 (see table) frequency doubler may be just the solution you are looking for. The isolation performance of these devices ensures that the input frequency (fin) and its harmonics 3fin and 4fin are attenuated by 35 dB relative to the wanted output frequency 2fin.
