CMD225C3 Multiplier

4-8 GHz (C Band) Input Passive Frequency Doubler MMIC

The CMD225C3 die is a broadband MMIC GaAs x2 passive frequency multiplier housed in a leadless surface mount (SMT) package. When driven by a +15 dBm signal, the multiplier provides 13 dB conversion loss at an output frequency of 12 GHz. The Fo and 3Fo isolations are >47 dBc and >54 dBc respectively. The CMD225C3 MMIC is a 50 ohm matched design eliminating the need for RF port matching.


  • Broadband performance
  • Excellent Fo isolation
  • Low conversion loss
  • No bias required
  • Pb-free RoHS compliant 3x3 mm SMT package
  • Positive gain slope

Custom MMIC Space Qualified MIMCs
Space Qualification

Custom MMIC strives to design all of our MMIC devices in a manner such that they can be readily chosen for your space application. We have an extensive history of successfully screening and qualifying our product to space applications per MIL-PRF-38534, MIL-PRF-38535, NASA INST standards and customer specific requirements. We collaborate with our customers to determine the appropriate screening and qualification based on their specific mission. Our space product screening and qualification are performed in-house and with approved partners. Whether you are looking for a space screened die, hermetically sealed packaged product or non-hermetic packaged product, Custom MMIC is prepared to help you address your qualification requirements
