Abstract :
A monolithic three-stage resistive-feedback amplifier has been developed for the 2-8-GHz band. This amplifier uses a novel approach which incorporates three stages with varying FET gate widths. The measured gain is 19 ± 1 dB and the VSWR is 2.3:1 in this band. The amplifier chip has a noise figure of ∼6 dB over the bandwidth. The chip size is less than 2.0 × 1.6 mm2and includes the bias circuitry. The amplifier also has AGC capability with more than 20 dB of gain control.
