Description

The MM1-1850SSM is a GaAs MMIC double balanced mixer that operates at high frequency in a proprietary surface mount package. MM1-1850SSM is a K/Ka band mixer that works well as both an up and down converter. This mixer offers exceptionally high frequency RF bandwidth for a surface mount mixer and high spurious suppression. The sister MM1-1850HSM is recommended for lower LO power applications. The MM1-1850SSM is available in a proprietary 4x4 mm package. Evaluation boards are available.

Specifications

The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for a down conversion application with the LO driven with an AMM-6702UC with +10 dBm input power biased at +4/-0.4V. Specifications shown for configuration A. Configuration B may be suitable for conversions below 45 GHz.
