The upper half is shifted down to 4-22 GHz with a single block conversion using high side injection at 44 GHz. Gain is provided along the way as needed. All components are on hand and have been characterized. Mounting bracket is finished and RF converters are now being installed. The square law detectors that provide a measure of the power in each channel follow the filters.
All components are on hand and are being tested.
The low loss, high frequency cable, which interconnects the RF and IF section, is ready for installation. The rack mounted box are being assemble, one for each IF module. UC Davis is working on providing an integrated video amp, RF detector, and IF amp module. The first prototype module should be available in the near future. These boards have a gain of 100 and a bandwidth of 1MHz.
