Abstract

A variable gain MMIC amplifier block is demonstrated.A maximum gain of 13 dB with a control range of 13 dB is obtained at 2.5GHz.The –3dB bandwidth is 5 GHz.The circuit consists of a cascade input stage with an active load followed by a source follower for impedance transformation.A GaAs pseudomorphic HEMT technology is used for the implementation.The active circuit area is less then 0.5 mm 2.
