Hujung hadapan penerima kriogenik jalur 2-GHz eksperimen yang sangat rendah dan sangat terpilih (CRFE) telah dibangunkan baru untuk stesen pangkalan selular. Ia menggunakan penapis superkonduktor Q tinggi, penguat kriogenik hingar yang sangat rendah, dan penyejuk yang sangat boleh dipercayai yang sangat padat. Reka bentuk asas CRFE disiasat. Pertama, suhu hingar setara CRFE dan kesan meningkatkan sensitiviti CRFE pada penerimaan stesen pangkalan dibincangkan. Seterusnya, teknologi penting dan ciri asas setiap komponen diterangkan. Akhir sekali, pengaruh bunyi antena, seperti bunyi tanah dan bunyi buatan manusia, dianggarkan melalui ujian lapangan di kawasan bandar dan pinggir bandar.

vol. E83-B, no. 8, pp. 1834-1843, August 2000, doi: .
Abstract: An ultra low-noise and highly selective, experimental 2-GHz band cryogenic receiver front end (CRFE) has been newly developed for cellular base stations. It utilizes a high-Q superconducting filter, a very low noise cryogenic amplifier, and a highly reliable cooler that is very compact. Fundamental design of the CRFE is investigated. First, the equivalent noise temperature of the CRFE and the effect of improving CRFE sensitivity on base station reception are discussed. Next, essential technologies and fundamental characteristics of each component are described. Finally, influence of antenna noise, such as ground noise and man-made noise, is estimated through field tests both in urban and suburban areas.
