Chelmsford, MA — Hittite Microwave has introduced a GaAs MMIC Active x2 Frequency Multiplier chip that allows radio designers to achieve continuous output frequency coverage from 22 to 46 GHz. This Active x2 Frequency Multiplier also provides excellent fundamental and subharmonic suppression in clock generation, point-to-point radio, military and space, VSAT, and test equipment applications.
The HMC598 utilizes GaAs PHEMT technology, and is offered in bare die form. The device is comprised of an input amplifier, a low conversion loss frequency doubler, and an output buffer amplifier. When driven with a +5 dBm input signal, this frequency 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 high output power capability of the HMC598 also allows designers to conveniently drive many of Hittite's Double-Balanced and I/Q MMIC Mixer products directly.
The HMC598 Active x2 Frequency Multiplier may be used to build clock generation circuits implementing OC-768 and STM-256 optical standards. Also ideal for use in LO multiplier chains for point-to-point and millimeterwave radios, the device requires no external components and only standard bias decoupling capacitors, yielding a reduced parts count compared with traditional design approaches. The die operates over the -55 to +85C temperature range.
A datasheet is available.
