This paper describes about design & development of a Quad channel single stage down converter receiver architecture. This receiver module is a part of ERP unit that forms a major entity for Tracking Radar operating at Ka band frequency. The tracking radar front end receiver receives target echo from antenna, amplifies it, and down converts it to IF1 frequency in S band. This forms input to each channel of Quad IF receiver that down converts it to lower IF2 frequency of 120MHz for further processing after amplification & filtering. The major challenge for designing this receiver was to meet key specifications which are Image rejection, Isolation between channels, Gain & phase tracking between channels and Noise figure that were to be met over temperature (-20ºC to+ 55ºC). This paper gives insight about design considerations to meet some of these key receiver specifications.
