CMD285C3

DC-20GHz Voltage Variable Attenuator

The CMD285C3 is DC to 20 GHz GaAs MMIC absorptive Voltage Variable Attenuator (VVA) housed in a leadless surface mount package ideally suited for military, space and communications systems. The VVA uses two analog control voltages varied between -5V and 0V to control RF signal levels over a 35 dB dynamic range. The CMD285C3 has a low insertion loss of 3.2 dB at 10 GHz and is a 50 ohm matched design, eliminating the need for RF port matching.

Features

  • Wideband performance
  • Low insertion loss
  • Wide attenuation range
  • High linearity
  • Pb-free RoHS compliant 3x3 mm SMT package

Custom MMIC Space Qualified MIMCs
Space Qualification

Custom MMIC strives to design all our MMIC devices in a manner such that they can be readily chosen for your space applications. We offer turnkey space screening / testing service when a device is categorized as "Ready for Space Screening" on our website. In some cases, our devices have already been "Space Qualified" or "Mission Specific" and are often available from stock. Our "Mission Specific" devices are screened based on custom applications where screening is derived from MIL requirements and tailored specific to customer needs. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
