Title: Transmission circuit device
Inventor: FURUTA TAKESHI
IPC: H03F3/50
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To simplify and miniaturize a transmission circuit device by preparing a power amplifier circuit which amplifies the signals transmitted via a transmission line and a branch line, consisting of only a passive element which sets free the signal of a prescribed level from a signal line. SOLUTION: An FET(field effect transistor) 108 included in a signal line controls the gains from a signal input terminal 101 through a signal output terminal 102. A matching circuit 111 consists of the passive elements such as a capacitor, an inductor, etc., to operate for impedance matching of signals to be transmitted to the terminal 102 from the terminal 101, when the FET 108 is turned on by the voltage supplied from a power control terminal 104 and then to operate for the impedance matching of an attenuator and a path that makes the cut electric power fore from the signal line to GND, when the FET 108 is turned off respectively. Thus, the electric power can be controlled in a matched state, and a simple and compact circuit is available with a small chip area in comparison to the use of an active circuit.
