Problems associated with high sensitivity electromagnetic radiation measurements arise when low levels of broadband radiated emissions are to be detected. Such measurements require expensive and sensitive equipment operating in a broad range of frequencies. This paper presents an inexpensive broadband amplifier designed to increase the overall gain of a measurement system consisting of a 50 ohm broadband antenna coupled to a 50 ohm input spectrum analyzer. Addition of the amplifier increases system gain by nearly 30 dB with insignificant degradation in the signal-to-noise ratio. The bandwidth of the system exceeds 1000 MHz, with the frequency ranging between 30MHz and 2.2GHz.
