| 内容記述 | The Echo I satellite receiving system at the Bell Telephone Laboratories facilities at Holmdel, New Jersey, required a 2390-Mc standby receiver system to maintain operation during possible failures of the primary maser receiver. This paper describes the details of the two matched parametric amplifiers that were used to provide the standby receiver. The use of this system in the initial Moonbounce experiments and in Project Echo is described. The details of an emergency operation at the beginning of a balloon pass are also presented. |
