Heterodyne detection of infrared radiation by cryogenically cooled extrinsic photoconductors is reviewed. Operational characteristics of a highly compensated Ge:Hg detector are calculated from experimentally determined material parameters. In many cases wideband, quantum noise limited performance can be obtained only if substantial refrigeration capacity is available at detector operating temperature.
