The new mixer design goals have been fixed as follows:
The principal feature of this design is the use of individual inductive
tuning of the SIS junctions and optimization of the mixer circuit
elements, with the aim of having a simple tuning for the SSB operation
and of insuring the stability of the receiver operation in SSB mode
across the RF band.
Special attention has been paid to get the optimal operation around
the most commonly used frequencies, 220 and 230 GHz.
- Low noise operation in the frequency range 210 - 245 GHz LO.
- SIS mixer should be tunable to single sideband operation in the whole
210--245 GHz band.
- Stable receiver output power in DSB and SSB operation.
