Hittite Launches Active x2 Frequency Multiplier with Output Frequency Range up to 46GHz [Copy link]

Hittite Microwave, a provider of complete MMIC (monolithic microwave integrated circuit) based solutions for communications and military applications, has introduced seven new active x2 frequency multipliers that enable radio designers to achieve a continuous output frequency range of 5 GHz to 46 GHz, all with excellent fundamental and subharmonic suppression in point-to-point, point-to-multipoint, VSAT and military applications.

The HMC576, HMC578, and HMC579 active x2 frequency multipliers are available in die form and consist of an input amplifier, a low conversion loss doubler, and an output buffer amplifier. These active x2 frequency multipliers operate with an input drive level of +3dBm and can provide output powers of +12dBm to +16dBm. Using three of these active x2 frequency multipliers, radio designers can achieve a continuous output frequency range of 18GHz to 46GHz.

For applications requiring SMT RoHS-compatible packaging, the HMC575LP4(E), HMC576LC3B, HMC577LC4 and HMC578LC3B active x2 frequency multipliers can provide output frequencies from 5 GHz to 33 GHz.

These new frequency doublers have increased output power capability, with a range of +12dBm to +21dBm, allowing designers to use these doublers to directly drive many of Hittite's double-balanced mixers and I/Q MMIC mixer products. The HMC578LC3B is ideal for driving the LO port of the new HMC560LM3 24GHz to 40GHz double-balanced mixer, and it also provides several dB of output power margin, allowing designers to place a bandpass filter between the two components if necessary.

Samples and evaluation PCBs for all SMT packaged products are available now and can be ordered by visiting Hittite Microwave's e-commerce website or by placing an order directly. Published product data sheets are available online at www.hittite.com.
