Abstract :
The relationship between low-frequency dispersion and the intermodulation performance of AlGaAs/GaAs HBTs has been demonstrated for the first time. The theoretical analysis and experimental results indicate that IM/sub 3/ will depend strongly on the frequency spacing (/spl Delta/f=f/sub 2/-f/sub 1/) in the two-tone measurement.
