We demonstrate high bandwidth and low-noise readout of a superconductor–insulator–normal metal–insulator–superconductor hot-electron bolometer element. We measure a noise equivalent temperature of better than 0.6 μK/Hz1/2 and infer an electrical noise equivalent power of 7×10-17 W/Hz1/2 for a normal-metal volume of 4.5 μm3 at an operating temperature of 270 mK. Using a pulsed bias technique we measure a thermal time constant of 1.2 μs at 270 mK. The microwave readout method we employ is compatible with large-format arrays of 103–105 pixels required by future far-infrared space and ground-based observatories.
