Abstract :
A wideband distribution amplifier that has a high degree of automatic gain control, low environmental sensitivity, and very good isolation between channels is described. It performs within design specifications from 100 kHz to 10 MHz without tuning or operator adjustment. Interchannel isolation of better than 100 dB is combined with low phase noise and low harmonic distortion. The amplifier has been designed to be operated in a VXIbus environment to allow its inclusion in larger distribution systems. The block diagram of the amplifier is given, and measured performance data are presented. A novel method of measuring interchannel isolation is also described
