摘要: This paper presents a pre-amplified detector receiver based on 250 nm InP/InGaAs/InP double heterojunction bipolar transistor (DHBT) process available from the Teledyne scientific. The front end consists of slot antenna followed by five stage low noise amplifier and detector, all integrated onto same circuit. Results measured responsivity are presented. is characterized through measuring its response to hot (293) cold (78) K terminations. Measurements voltage spectrum at video output presented can be used derive temperature resolution for specific bandwidth.
