Device Overview
General Description
M8 mixers are hybrid assemblies that use a specially balanced technique to feature very low conversion loss and high isolations. M8 mixers have generally been replaced with MM1 mixers with superior performance, repeatability, and availability. M8 mixers are still used in legacy systems and are suitable for laboratory use.
Features
- LO/RF 4.0 to 12.0 GHz
- IF DC to 2.0 GHz
- 5.0 dB Typical Conversion Loss
- 40 dB Typical LO to RF Isolation
- Multi-Octave RF and LO
- Superior Bi-Phase Performance
