ABSTRACT:
An amplifier is disclosed which is capable of operation from 0 MHz to over 100 MHz with very low distortion over this entire range. Several inputs may be combined without affecting the gain of the amplifier. Several outputs may be combined without adding to the distortion products significantly. A pair of common-base symmetrically juxtaposed transistors drives a pair of symmetrical common-emitter transistors. An AC and DC feedback loop is provided along the line of symmetry. In addition, each symmetrical half of the set of four transistors has a DC feedback loop which balances current between stages of said half and inhibits overcurrent conditions in the transistors of that half.
