CMD256

Overview

The CMD256 is a broadband MMIC GaAs x2 passive frequency multiplier designed for high-frequency applications. It operates within the 14 GHz to 20 GHz output range, corresponding to an input frequency of 7 GHz to 10 GHz. The device features a 50-ohm matched design, which eliminates the need for external RF port matching networks. When driven by a +15 dBm signal, the multiplier provides 15 dB conversion loss at the 14 GHz output frequency. Key technical attributes include low conversion loss, excellent Fo isolation, and broadband performance characteristics suitable for demanding RF systems.
