| Abstract: | In this paper we describe a sort of single-stage dual-gate FET electronic tuning amplifier. The electronic tuning range is from 970 MHz to 1470 MHz.The 3dB tuning bandwidth and the noise coefficient are less than 90MHz and 2.5dB, respectively. The gain is not less than 10dB. Applying it to the input of the second mixer of the TV receiver for satellite broadcasting, we can improve the capability of supressing the image interference by about 20dB. |
