ABSTRACT :
The Berkeley-Illinois-Maryland Array (BIMA) and
the Caltech Owens Valley Radio Observatory Array telescopes will merge to form
the Combined Array for Research in Millimeter-Wave Astronomy (CARMA) in 2005.
Each element of the new telescope1 will be equipped with a cooled 1 mm receiver
consisting of a Superconductor-Insulator-Superconductor (SIS) mixer with
Intermediate Frequency (IF) postamplifier. Downconverted signals from each
element will be processed by a correlator with a total bandwidth of 4 GHz.
Whereas the current OVRO 1 mm receivers2 cover a 4 GHz IF band, from 1 - 5 GHz ,
the present BIMA receivers use IF postamplifiers which cover only 1.4 – 2.2 GHz
(L band). Before integrating BIMA instrumentation with CARMA, receiver IF
bandwidths must be expanded to at least the CARMA correlator bandwidth. The
resulting wide instrumental bandwidth will greatly facilitate the study of
molecular transitions and continuum radiation. This paper describes our progress
towards building wideband receivers by combining existing 1 mm SIS mixer chips
developed for BIMA with 0.5 – 11 GHz MMIC amplifiers developed for the Allen
Telescope
Array.
