Title: High frequency changeover device
Inventor: TAKAYA TAKUYA
IPC: H01L29/812
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To enhance the performance of a high frequency changeover device by using a transistor(TR) built up to suppress its characteristic dispersion while taking dispersion in the physical shape of the TR into account to a degree. SOLUTION: A field effect TR 15, whose drain terminal D is connected to a stub 14 and whose source terminal S is connected to ground, is employed for the high frequency changeover device acting like a high frequency two-way switch with one input and one output. When the TR 15 is turned on, a high frequency signal is transmitted through the high frequency changeover device and when the TR 15 is turned off, the high frequency signal is shut off. A high electron mobility TR(HEMT) is adopted for the TR 15, its gate electrode is offset toward its source electrode so that a distance between the gate electrode and its drain electrode is larger than a distance between the gate electrode and the source electrode. In this case, dispersion in a gate-drain capacitance Cgd is reduced, resulting in reduced dispersion in a phase of a reflection coefficient S22 at an output of the TR.

Abstract: PURPOSE:To drive a coil with a stable current even if supplied energy becomes unstable when the current is conducted to the coil, by driving the coil with the current corresponding to an indicating voltage, which is increased at a sepcified time constant that is generated by an indicating voltage generating means. CONSTITUTION:A current-conduction energizing circuit 32 energizes the current conduction of a hammer solenoid coil 31 for a specified time period in accordance with a driving time information, which is read out of an ROM 16. A current detecting circuit 30 detects an exciting current Il flowing though the coil 31 by a resistor r8 and converts the current into a detected voltage V2. A time constant circuit 27 increases an indicating voltage V1, which is generated in correspondence with the energizing of the current-conduction energizing circuit 32 at a specified time constant. A voltage follower circuit 28 drives the coil so that the detected voltage V2 of the current detecting circuit 30 agrees with the indicating voltage V1 of the time constant circuit 27. Therefore, even if a power source voltage is changed slightly, the coil can be stably driven with the constant current having a specified current value.
