Abstract

An amplifier array for high-frequency signals includes a differential amplifier with transistors capacitively coupled to the emitters. The differential amplifier therefore has high-pass characteristics. The input signals are each supplied to the differential amplifier through a respective high-pass. This results in an integratable amplifier array with strong damping for base-band signal components and band-pass characteristics for high-frequency useful signal components.
