MMIC Multiplier Uses GaAs PHEMT Technology
Thu, 10/09/2008 - 6:03am
Hittite Microwave Corporation introduces its Model HMC598 GaAs MMIC Active x2 Frequency Multiplier chip which allows radio designers to achieve continuous output frequency coverage from 22 to 46 GHz. This multiplier also provides optimal fundamental and sub-harmonic suppression in clock generation, point-to-point radio, military and space, VSAT and test equipment applications. The multiplier uses GaAs PHEMT technology, and it is offered in bare die form. It is comprised of an input amplifier, a low conversion loss frequency doubler and an output buffer amplifier. The multiplier can be used to build clock generation circuits, implementing OC-768 and STM-256 optical standards. It is also suitable for use in LO multiplier chains for point-to-point and millimeterwave radios.
