Description

M/A-COM’s MD-189 and MDS-189 are high level
termination insensitive mixers. These devices are packaged
in 8-lead flatpack and SMT packages. These mixers offer
consistent and repeatable flat intermodulation performance
and flat conversion loss with low spurious signal generation
independent of system mismatch from 1 to 3500 MHz. The
MD-189 and MDS-189 are ideally suited for RF/IF
communications applications requiring high intercept point
performance.
