Abstract :
A low noise, high dynamic range wide-band amplifier matching either a telescope or a wire antenna for SW receivers is presented. The amplifier features low noise, low distortion and rail to rail swing capability. With 5 V single supply, a signal of 4 Vρρ can be driven into 500 Ω/110 pF load. For the wire antenna, the measured equivalent input noise is 025 μVrms within 25 kHz IF band and a high dynamic range of 135 dB is achieved. For the telescope antenna, the measured noise is 0.21 μVrms and the dynamic range is 136 dB without the use of any AGC.
