• Full Waveguide Band Coverage

• Low Conversion Loss

• High LO to RF Isolation

• Variety of IF Bands

QuinStar Technology's QMB series balanced mixers enable millimeter-wave signals to be down converted to broad IF bandwidths with a local oscillator. They are available for RF over 18-110 GHz in seven waveguide bands and operate over very broad RF, LO and IF bandwidths.

For fixed LO frequency applications, a very wide IF range may be provided if desired. The local oscillator waveguide port may be in either the same waveguide band as RF waveguide port, or in lower or higher waveguide bands (the two adjacent bands). For IF above 18 GHz, a K-connector is provided on the IF port.

NOTES:
1. Local oscillators (LO) drive level required is 11.0 dBm minimum, 13 dBm typical (nominal) and 17 dBm max.
2. LO to RF isolation is 20 dB typical.
3. LO to IF isolation is 40 dB typical for LO above RF range and is 20 dB min. for LO below the RF range.
