A compact 1.3 mm × 0.83 mm SiGe distributed wideband amplifier is presented. The design utilizes highly lossy thin film microstrip transmission line elements. Attenuation compensation methods for extending the amplifier's bandwidth are discussed. Amplifier small-signal gain is 10.5 dB, upper 3 dB cut-off frequency is 41 GHz. Low group delay variations of 21 ps within the bandwidth qualify this amplifier for operation in a 40 Gbit/s fibre-optic communication system.
