There is a strong interest in the Submillimeter community to increase the IF bandwidth of SIS receivers in order to facilitate extra-galactic astronomy. However, increasing the IF bandwidth generally also means increasing the IF operating frequency of the mixer, because it is very difficult to achieve a good IF impedance match to a low noise amplifier (LNA) for more than an octave bandwidth. Co...

Generally, analog RF front-end circuits are designed to be functional under the most stringent, fixed, operating conditions, where all the performance parameters are set by crude hardware design in a fixed way. The figures of merit, resulting from such a design approach, related to only one operating condition and to only one design point, are the already existing, standard or fixed figures of ...
