Functional Diagram
General Description
The HMc598 is a x2 active broadband frequency
multiplier chip utilizing GaAs PHEMT technology.
When driven by a +5 dBm signal, the multiplier
provides +15 dBm typical output power from 22 to
46 GHz and the Fo and 3Fo isolations are 25 dBc
and 15 dBc respectively at 30 GHz. The HMc598 is
ideal for use in LO multiplier chains for Point to Point
and vSAT radios yielding reduced parts count versus
traditional design approaches.
