This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. This subproject (phase 3) is intended to implement a cryogenic receiver. For this receiver system we require a cryogenic low-noise amplifiers (LNA) for Ku and Ka frequency bands from a company (e.g. Spacek Labs, Inc.) with the reputation for building such devices for Radio Astronomy and space. The LNA input will be protected with a custom-built cryogenic receiver protector switch. The cryogenic LNA, switches, and probe-head will be mounted on a carrier plate, housed by the developmental cryostat. Components external to the cryostat include Ka-band transceiver, electronics presumably comprised of DSP-controlled ACERT BN2 pulse programmer, and the AP240-based data acquisition system.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 这个分项目（第3阶段）的目的是安装一个低温接收器。对于该接收器系统，我们需要来自公司（例如，Spacek Labs，Inc.）的用于Ku和Ka频带的低温低噪声放大器（LNA）。以建造射电天文学和太空设备而闻名。LNA输入将由定制的低温接收器保护开关保护。低温LNA、开关和探头将安装在载板上，由开发低温恒温器容纳。低温恒温器的外部组件包括Ka波段收发器、可能由DSP控制的ACERT BN 2脉冲编程器组成的电子设备以及基于AP 240的数据采集系统。
