Custom MMIC adds GaAs-based frequency multipliers spanning 8-40GHz

Monolithic microwave integrated circuit (MMIC) developer Custom MMIC of Westford, MA, USA has expanded its standard product portfolio with three new frequency multipliers/doublers. The firm's multiplier family now covers output frequencies of 8-40GHz, with both passive and active architectures. The active multipliers offer high output power for driving mixers directly, while their passive counterparts offer low phase noise with a lower output power.

The CMD213 is a broadband x2 active frequency multiplier available in die form that covers an input frequency range of 8-15GHz input. It offers high output power, and its 46dBc Fo isolation surpasses that of its competitors. When driven by a +17dBm signal, the CMD213 provides +17dBm output power at 30-40GHz. The Fo isolation is greater than 46dBc at 35GHz. Its 50 ohm matched design eliminates the need for external DC blocks and RF port matching. 

The CMD226 and the CMD227 are broadband x2 passive frequency multipliers available in die form with input frequency ranges of 7-11GHz and 8-15GHz, respectively. Both offer low conversion loss, what is claimed to be superb Fo isolation, and no additive phase noise, making them suitable for synthesizer circuits. The 50 ohm matched design eliminates the need for RF port matching.

When driven by an input signal of +15dBm, the CMD226 provides 10.5dB conversion loss at an output frequency of 18GHz, and the Fo and 3Fo isolations are 44dBc and 46dBc respectively. Similarly, when driven at an input signal level of +15dBm, the CMD227 provides 11dB conversion loss at an output frequency of 23GHz, and the Fo and 3Fo isolations are 40dBc and 43dBc respectively.

Typical applications for Custom MMIC's family of frequency multipliers/doublers include military radar/EW (electronic warfare), point-to-point radios, VSAT, and test instrumentation.
