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.

该子项目是利用资源的众多研究子项目之一 由 NIH/NCRR 资助的中心拨款提供。子项目的主要支持 并且子项目的首席研究员可能是由其他来源提供的， 包括其他 NIH 来源。 子项目可能列出的总成本 代表子项目使用的中心基础设施的估计数量， NCRR 赠款不直接向子项目或子项目工作人员提供资金。 该子项目（第三阶段）旨在实施低温接收器。对于该接收器系统，我们需要一家公司（例如 Spacek Labs, Inc.）提供适用于 Ku 和 Ka 频段的低温低噪声放大器 (LNA)，该公司在为射电天文学和太空制造此类设备方面享有盛誉。 LNA 输入将通过定制的低温接收器保护开关进行保护。低温 LNA、开关和探头将安装在由开发低温恒温器容纳的载板上。低温恒温器外部的组件包括 Ka 波段收发器、可能由 DSP 控制的 ACERT BN2 脉冲编程器组成的电子器件以及基于 AP240 的数据采集系统。
