Device Overview
General Description
The MMD-1250H is a MMIC millimeter wave doubler fabricated with GaAs Schottky diodes. This doubler operates over a guaranteed 6 to 25 GHz input frequency range or a doubled output frequency range of 12 to 50 GHz. It features excellent conversion loss, superior isolations, and harmonic suppressions across a broad bandwidth. Both the wire bondable die and connectorized units are available.
Features
- High fundamental rejection
- Millimeter wave output frequencies
- Low 2F Conversion Loss
Applications
- High frequency synthesis
- LO signal chain

Electrical Specifications
The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for the connectorized U package doubler used in the forward direction with a +14 dBm sine wave input. Min and Max limits apply only to our connectorized units and are guaranteed at TA=+25°C. RF testing of our die is performed on a sample basis to verify conformance to datasheet guaranteed specifications.
