Abstract
A GaAs monolithic voltage-controlled attenuator and a vector attenuator, wh ich apply a ring structure, are newly developed. Their features are a very small size, which permits dense integration, and a large-scale variable ran ge. Because of using lumped constant topologies and adopted a MESFET instea d of a p-i-n diode as variable resistor, the size of the circuit is reduced greatly. The chip sizes of the voltage-controlled biphase and vector atten uator are 4.5 mm X 1.5 mm and 7 mm X 1.5 mm, respectively. (C) John Wiley & Sons, Inc.
