Custom MMIC has expanded its standard product portfolio with three new frequency multipliers/doublers. The Multiplier family now covers output frequencies from 8 GHz to 40 GHz, 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. Typical applications for these multipliers include military radar, Electronic Warfare, point-to-point radios, VSAT, and test instrumentation.
The CMD213 is a broadband x2 active frequency multiplier available in die form that covers an input frequency range of 8 to 15 GHz input. The multiplier offers high output power, with 46 dBc Fo isolation. When driven by a +17 dBm signal, the CMD213 provides +17 dBm output power from 30 to 40 GHz. The Fo isolation is greater than 46 dBc at 35 GHz. 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 to 11 GHz and 8 to 15 GHz, respectively. Both multipliers offer low conversion loss, superb Fo isolation, and no additive phase noise, thus making them ideal for synthesizer circuits. The 50 ohm matched design eliminates the need for RF port matching.
When driven by an input signal of +15 dBm, the CMD226 provides 10.5 dB conversion loss at an output frequency of 18 GHz, and the Fo and 3Fo isolations 44 dBc and 46 dBc respectively. Similarly, when driven at an input signal level of +15 dBm, the CMD227 provides 11 dB conversion loss at an output frequency of 23 GHz, and the Fo and 3Fo isolations are 40 dBc and 43 dBc respectively.
