Broad Band Mixers
L
orch Microwave’s Broad Band Mixers, Series FC, are
available in a wide range of LO drives. They are optimized
to cover the frequency range from 0.05 to 4000 MHz. Low
conversion loss and high isolation are achieved by the use
of low-loss ferrite networks together with specially
matched Schottky barrier diode quads.

Notes:
1) Nominal impedance is 50 Ohms.
2) DC polarity is negative.
Standard units are designed to provide optimum performance over the
full frequency range listed. If the band of interest is narrower, it should
be indicated when ordering (See “Creating a Part Number”).
Performance will be optimized over the band of interest and improved
performance may be offered at no extra cost.
