本文介绍了一种微波接收机，它是由天线、平衡混频器和中频放大器集成在一个公共基片上组成的。每个接收器都足够小，以使二维阵列能够在单个半导体芯片内单片制造。每个接收器的天线方向图适合于通过介电浸没透镜馈电，从而在远场中产生高增益波束阵列。这样的接收器已经被构建为在10和35 GHz下工作，并且显示出与更传统的设计类似的转换损耗。
A family of microwave receivers is described which consists of antennas integrated with a balanced mixer and IF amplifier on a common substrate. Each receiver is small enough to enable two-dimensional arrays to be fabricated monolithically within a single semiconductor chip. The antenna pattern of each receiver is suitable for feeding via a dielectric immersion lens, thereby creating a high-gain array of beams in the far-field. Such receivers have been built to operate at 10 and 35 GHz, and show conversion loss similar to more conventional designs.
