PROBLEM TO BE SOLVED: To obtain an active signal distribution circuit for a broadcast receiver which prevents signal quality from being degraded in a conventional active distribution circuit and provides a sufficient separation performance between output terminals by solving the problem such as nonlinear distortion of amplification characteristics of an active element that is a problem of the conventional active distribution circuit by eliminating occurrence of power loss that is a defect of a passive type in a signal distribution circuit of a broadcast receiver. SOLUTION: Bases and emitters of a plurality of high frequency transistors 11, 12 are connected in common, respectively and collectors are connected to independent output terminals 16, 17, respectively. The common-connected emitters are connected to a common input terminal 15, and the commonly connected bases are connected to a common bias source 13 made into a cold potential by a capacitor 14. An external power source Vcc is connected via a resistor between the collectors of the transistors 11, 12 and the respective independent output terminals. COPYRIGHT: (C)2006,JPO&NCIPI
