Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a GaAs MMIC x2 Active Frequency Multiplier which is ideal for Point-to-Point and Point-to-Multipoint Radios, VSAT, Telecom, Test Instrumentation, Military, Space and Fiber Optics applications from 8 to 21 GHz. The HMC561 is a broadband x2 Active Frequency Multiplier die which utilizes GaAs PHEMT technology and accepts input drive levels from 0 to +6 dBm. When driven with a +5 dBm input signal, the HMC561 provides +17 dBm typical output power from 8 to 21 GHz, and the Fo and 3Fo isolations are 15 dBc. This compact MMIC multiplier also delivers low additive SSB Phase Noise of -139 dBc/Hz at 100 kHz offset, making it ideal for use in LO multiplier chains for Point-to-Point and Point-to-Multipoint Radios. The HMC561 is ideal for driving the LO port of many of Hittite’s mixers, including the HMC523 GaAs MMIC I/Q Mixer, which operates from 15 to 23.6 GHz. The HMC561 x2 Active Frequency Multiplier die is also available in a RoHS compliant 3x3mm leadless QFN package as the HMC561LP3. These multipliers complement Hittite’s broad line of active and passive frequency multipliers which cover output frequencies from 1.4 to 46 GHz. Samples are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
