Abstract
A monolithic integrated amplifier in HFET-Technology for the 27 GHz band is presented, fitted for the use in digital radio link front ends with dedicated in- and out-of-band specifications. The amplifier consists of two stages of 0.5 mym HFETs and some passive circuitry for matching, biasing and gain stabilizing. Coplanar waveguides and lumped elements like thinfilm resistors, MIM-capacitors and spiral inductors were used. All passive and active components were measured separately and the derived circuit models were placed into a CAD-library.
