Title: Low-noise amplifier and control circuit thereof
Inventor: KIRISAWA AKIHIRO
IPC: H03F3/72
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To have resistance to input in non-operation state at the time of transmission or reception standby improved in all frequencies, without deteriorating the noise temperature in a low-noise amplifier of a reception part of a portable communication terminal and the like. SOLUTION: At the time of power source interrupt, a gate voltage of an HEMT or an MES FET is made to be shifted below a pinch off voltage by transistors 13 and 15, and this amplification element is made to be pinched off. At this time, a drain current ceases to flow and a power consumption becomes zero. Also, at this time, since the gate voltage is biased to a negative side, a forward voltage will not flow between the gate and the source of the transistors 13 and 15 of the amplification element, even if an excessive input signal enters. Thus, resistance to input is made improved at the transmitting and receiving standby, and the deterioration and the possibility of destruction of the device are reduced.
