Model BDC-28 |
Description
A range of broadband down converter modules from 26.5 – 110 GHz have been developed based on the successful BMC-series of balanced mixers and temperature stabilised GN-series Gunn Oscillators. These block down converters allow existing microwave hardware such as receivers, test equipment, etc, to be extended into the mm-wave spectral region. Low noise figures are achieved over greater than 15 GHz bandwidths and the temperature stabilised Gunn oscillators provide stabilities of the order ±35 MHz over an operating range 15-25ºC (eg. BDC-28 Model).
Higher stability local oscillators such as PLDRO's can also be provided. As standard, image rejection filtering is integral. |
