The conventional or direct detection Bragg Cell Spectrum Analyzer, or simply Bragg Cell receiver (Figure 1), is useful in defense related applications, the reason being that real time spectral analysis of RF signals is an important element of electronic warfare and surveillance. For such applications, wide bandwidth (up to 1 GHz) and high frequency resolu-tion (≈1 MHz) are desirable features and they have indeed been exhibited by experimental Bragg Cell receivers. Wide dynamic range, eg, 50 to 60 dB, is yet another matter. To date, achievable dynamic range has probably been about 30 dB, or perhaps even 40 dB. To understand the source of the dynamic range limitation and also to set the stage for the new receiver architecture which will be discussed, we will first review some Bragg Cell receiver principles.
