This SLIM is constructed on a common printed wiring board, the PWB-MXR-ADE.  Click to get full information on this Mixer PWB.

    The SLIM-MXR-1 is configured with the Minicircuits, ADE-11X.  This mixer was originally designed to be used as the first mixer in the MSA.  This mixer has only a fair L port to R port isolation (mixer pin 3 to pin 6).  Minicircuits specifies it as -38 dBc, but I measure it closer to -30 dBc at 1000 MHz.  They specify the conversion loss at -7.5 dB.  I measured the conversion loss at -6.5 dB.  I continue to recommend this mixer, but only because of it's very low cost.

Revision A:
  Added a 2.5 dB attenuator network in the L port path to the mixer.  This provides a better impedance match between the LO input connector -  J1, and the mixer, which, improves the mixer isolation.  With this mod, the isolation will approach the specification of Minicircuits.
  This makes it necessary for the LO Drive to be approximately +10 dBm.  To use this module as a mid-drive (+7dBm), the attenuator must be removed.
