QuinStar offers Image-Reject or Single Sideband Mixers/Upconverters for applications in the 18-110 GHz frequency range. These mixers are specially designed and configured to meet specific performance needs of customer’s application. The construction of image reject and single sideband mixers involves a pair of balanced mixers and a set of hybrids for RF, LO and IF to create the required performance.

Figure 1 below shows various possible arrangements. These mixers can be offered with either fundamental or sub-harmonic LO (LO at half RF frequency). QuinStar can test and optimize the component assembly to meet the required specifications for these special purpose mixers.

QuinStar Series QBP phase modulators are specially optimized to generate bi-phase modulated output for digital signal input. A driver that converts the input digital data to appropriate drive levels for bi-phase modulation (with suppressed carrier) is also included with the mixer.

Both fundamental and second harmonic (LO at one half of output RF frequency) Bi-phase modulators are offered.
