The CHX2192-99F from United Monolithic Semiconductors is a GaAs based 2x Frequency Multiplier IC with an input frequency from 27 to 33 GHz and an output frequency from 54 to 66 GHz. It provides 11 dBm of output power for an input signal of 12 dBm. This device consumes 130 mA of current @ 3.5V of DC supply.
The CHX2192-99F multiplier is available as a chip (2.12 x 1.11 x 0.10 mm) and is manufactured using a pHEMT process with 0.15 micrometers gate length, via holes through the substrate, air bridges, and electron beam gate lithography. It is designed for a wide range of applications, from military to commercial communication systems.
