| Ամփոփում: | In this paper, we present our latest works on
developing the various generic technologies to find the innovative
solutions for constructing a heterodyne focal plane array, based
on the Superconductor-Insulator-Superconductor (SIS) mixer
technology. This includes the use of the planar superconducting
circuit technology to replace the commonly used bulky waveguides or optical components, therefore simplifying the radio
frequency (RF) operation and minimising the size of the array.
We will describe the design of a novel easy-to-machine feed
horn technology which enables deployment of large arrays with
minimal cost. This technology has been demonstrated successfully
and has since been deployed in various existing and up-coming
telescopes. We then demonstrate these capabilities by presenting
the design and built of a small pixel-count array near 220 GHz
range, combining both the E- and H-polarisation chains within
a single mixer block. Finally, we briefly describe our recent
works on the superconducting parametric amplifier technology
that could potentially replace the conventional semiconductor
amplifiers that are power hungry and dissipate large amount of
heat, which render the construction of large arrays difficult. |
