The CMD225C3 from Custom MMIC is a GaAs passive frequency multiplier with an input frequency from 4 to 8 GHz (8 to 16 GHz output frequency). It can be driven with an input power of 15 dBm and has a conversion loss of 13 dB. The frequency doubler has F1 and F3 isolations of above 47 dBc and 54 dBc respectively. It is matched to 50 ohms thereby eliminating the need for RF port matching. The CMD225C3 is ideal for low phase noise frequency synthesizers and local oscillators. It is available as a die or in a 3x3 m surface mount package.
