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 phased-array 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).
