A pyroelectric detector has been built and characterised for operation within W-band. The various characteristics reported include detectivity, responsivity, NEP, polarisation sensitivity, dynamic range, linearity, and reflectivity (vswr). The pyroelectric detector performs well at these wavelengths and as the detector is inexpensive to build, and is robust, it ought to find many an opportunity for use within millimetre-wave laboratories.
