First implementation of the heterodyne superconducting integrated receiver based on hot electron bolometer (HEB) mixer is presented. The flux flow oscillator based on long Josephson junction is implemented on one chip (size 4x4 mm2) together with the HEB-mixer coupled to twin slot antenna. Frequency range of 450-620 GHz has been realized with noise temperature of about 1000 K at 600 GHz for intermediate frequency of HEB-mixer 0-1 GHz. Direct response of the mixer at frequencies up to 2 THz is measured being actually the twin slot antenna characteristics included in quasioptical system integrated with HEB (taking into account the matching circuits for the coupling of the local oscillator).
