<p>The present invention relates to a novel use of cryoelectronic equipment (32, 72, 76) to implement an extremely sensitive and stable receiver front end (52) for UHF, microwave, and millimeter wave applications. The invention is particularly applicable to base station receivers in mobile radio systems, where the range and capacity of the systems are typically limited by the base station receiver sensitivity.</p> |
