【 摘 要 】

Synthetic Aperture Radar (SAR) is a well known technique for imaging the earth’s surface. This paper presents a wideband variable gain amplifier (VGA) which can be used in the direct conversion receiver (DCR) for SAR. This paper first introduces how to extract the important parameters i.e. gain, bandwidth and power consumption of the VGA from the overall receiver requirements. VGA has designed for 2.4GHz Bandwidth and simulations are done using 0.13um technology level-54 model files on HSPICE Simulator. The proposed VGA circuit has a variable gain of (4.43 – 15.14) dB and -3dB frequency falls at 2.398GHz. The power consumption is only 1.803mW and the supply voltage is about 1.8v.
