CMD213
30-40 GHz Active Frequency Doubler
Features
► High output power ► Excellent Fo isolation ► Broadband performance ► Small die size
Applications
► Point-to-point radios ► Point-to-multi-point radios ► Military and space ► Test instrumentation
Description
The CMD213 die is a broadband MMIC GaAs x2 active frequency multiplier. When driven by a +17dBm signal, the multiplier provides +17 dBm output power from 30 to 40 GHz. The Fo isolation is greater than 46 dBc at 35 GHz. The CMD213 is a 50 ohm matched design eliminating the need for external DC blocks and RF port matching.
