In order to achieve high gain and wideband with relative low dc power dissipation (Pdc), the combination of the conventional distributed amplifier (CDA) and the cascaded single-stage distributed amplifier (CSSDA) is utilized to the circuit. Moreover, the active variable termination resistor (AVTR) is adopted to adjust the flatness of gain. According to the experimental results, the proposed VGDA achieves a 21-dB peak gain with a 40-GHz 3-dB bandwidth (3.7-43.7 GHz), 18-dB gain control range (GCR), and 16° maximum phase variation. ? 2001-2012 IEEE. |
