An antenna and a receiver are needed to effectively receive microwave signals from the universe.
For such a receiver design, the experimental purpose and antenna characteristics should be considered.
In recent radio astronomy research, there is a demand for wideband multi-channel simultaneous observation of the receiver, and the design of a Compact Tripple Band Receiver is in progress.
In addition, this talk will introduce the design of a receiver for observation of CMB(Cosmic Microwave Background).
The receiver for CMB observation is very different from the conventional radio telescope receiver, and the design considerations are also different.
Finally, these receivers require cryogenic cooling during operation.
Various technologies and design methods for cryogenic cooling of receivers will be introduced.
