摘要

我们将回顾射电天文学中紧凑、集成模拟-数字-光子接收器的最新进展。利用许多新颖的架构技术，如数字校准的数字边带分离和极化合成，稳定振幅和相位的无反射滤波器，以及未格式化的串行数据链路，这些单元是焦平面阵列和相控阵馈源(paf)在任何频率的理想选择，以及在大m /小d干涉仪上具有成本效益的现场可更换前端模块。本文通过从l波段(1.2-1.7 GHz)到w波段(75-110 GHz)的实际例子说明了这些技术。

Compact cm-Wave and mm-Wave integrated receivers

We will review the latest advances in compact, integrated analog-digital-photonic receivers for radio astronomy. Utilizing a number of novel architectural techniques, such as numerically calibrated digital sideband separation and polarization synthesis, amplitude- and phase-stabilizing reflectionless filters, and unformatted serial data links, these units are ideal for focal plane arrays and phasedarray feeds (PAFs) at any frequency, as well as cost-efficient field-replaceable front-end modules on large-M/small-D interferometers. These techniques are illustrated in this summary paper via practical examples ranging from L-Band (1.2–1.7 GHz) to W-band (75–110 GHz).
