The concept of an active superconducting terahertz detector for array applications is based on the combination of an RFTES bolometer and a microwave preamplifier based on a DC SQUID within the common integrated circuit providing the maximum, theoretically possible, signal transmission from the sensor to the amplifier. The problems associated with the design and positioning of the amplifier, that restrict the functionality and sensitivity of the ultra-low temperature detector, are considered. For the first time, a method for connecting a SQUID amplifier to an RFTES bolometer using the principle of partial loads of a resonator has been proposed and analyzed. The presented electromagnetic model of the active detector is suitable for optimization of RFTES, MKID and other detectors using high-Q superconducting planar resonators.
