Ultra-fast Detecting Module with Integrated Cooler Controller
An AIP INTIR detection module combines ease of operation, high detectivity, and small dimensions of the device with a gigahertz pass band. Thanks to the use of advanced integration techniques, a HgCdTe photodetector, a four-stage Peltier cooler, and a broadband transimpedance amplifier were packaged into a hermetically sealed 14 pin Butterfly mount. This approach enabled minimization of the length of wire connections between the detector and the electronic system. That decreases the parasitic inductance of leads, which usually limits the high frequency signal transmission band.
Nevertheless, the selection of wire connection lengths requires a certain compromise, as placing the detector too close to a preamplifier will result in excessive transfer of heat from the PCB to the cooled detecting structure. The current solution offers a module response band exceeding 1.5 GHz, with the structure temperature of ~210 K. The first stage of the transimpedance amplifier was built with the use of high frequency discrete SiGe transistors. That enabled obtaining a wide pass band and retaining a low noise level, which translates into high detectivity offered by the INTIR module.
