Title: Receiving system
Inventor: OOYAMA TAKEKATSU
IPC: H04B1/06
Filed: 1982-06-25
Abstract: PURPOSE:To reduce distribution losses to both existing and stand-by receivers, and also to supply a signal in parallel, by executing bias control so that an attenuation quantity becomes minimum instead of a large value, when an output of the stand-by receiver is used. CONSTITUTION:The bias is applied to a diode attenuator 4 so that the attenuation quantity becomes larger than 3dB, for instance, 10dB. When the attenuation quantity is large like this, the impedance seeing the diode attenuator 4 from a circulator 3 becomes high, and the applied receiving signal is reflected at a loss of about 0.1dB. When a loss of the circulator 3 is 0.3dB, a loss extending from an output end of an input filter 2 to an input end of an existing receiver 7 becomes 0.7dB. On the other hand, a receiving signal which receives a loss of 10.3dB is inputted to a stand-by receiver 8. In this state, if the receiver 7 becomes faulty, the bias which becomes the minimum attenuation quantity is applied from a biasing circuit 6 to the attenuator 4 by a squelch signal of the receiver 7 in this case, and also the output is switched to the receiver 8.
