Abstract :
Cryogenic front end (CRFE) receivers consisting of a high temperature superconducting filter and a cooled low noise amplifier placed between a base station antenna and a receiver electronics can significantly increase coverage and capacity in the presence of interference. In this paper the development of a family of CDMA CRFEs (D 6-9 and M1) by Cryoelectra GmbH and their performance are presented.
