Title: Multichannel high-frequency signal supplying device and high-frequency switch device
Inventor: MIYAKE YASUYUKI
IPC: H03F3/68
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a multichannel high-frequency signal supplying device the switching ability of which does not deteriorate even when a large-output signal source is used and a high-frequency switch device. SOLUTION: To each branch line L (L1 and L2) which leads high-frequency signals generated from an oscillator 4 and branched by means of a branching circuit 6 to output ports P1 and P2, switch amplifiers 8 (8a and 8b) which conduct and disconnect the lines L and limit amplifiers 10 (10a and 10b) which limit the upper-limit power of the inputs to the amplifiers 8 are respectively connected. The saturated output power Pmax of the limit amplifiers 10 is set in such a way that the power Pmax becomes equal to or smaller than the gain compressing power P which is the input power when the small-signal gains of the switch amplifiers 8 drop by 1 dB or smaller (P>=Pmax). Therefore, even when the power supply to the lines L is large, the ratio between the output signal intensities at the conducting time and disconnecting time is not deteriorated, because the switch amplifiers 8 only operate in linear areas.

Title: Circuit for canceling glitch of gallium-arsenic switch
Inventor: SUEMATSU HIROTO
IPC: G01R33/36
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To negate a glitch brought about when a GaAs switch used as an RF gate is switched. SOLUTION: This circuit has GaAs switches 1, 2 acting as RF gates and inserted equivalently to two signal lines of a balanced circuit. After an RF input is converted by a transformer 1 to the balanced circuit, the input is gated by the GaAs switches 1, 2 and the RF gate outputs are returned by a transformer 2 to an unbalanced circuit to be outputted as an RF output. In other words, after the RF input is converted to the balanced circuit, the GaAs switches are inserted equivalently to two RF lines, thereby negating glitches brought about thereto. A glitch voltage to the RF lines is accordingly reduced.

Filed: 1978-07-31
Abstract: PURPOSE:To simplify the constitution of the exchange side as well as to increase the circuit using efficiency by supplying the count output to the gate circuit after restart of the clocking at the counter and then cutting off the talking circuit with the count output. CONSTITUTION:Hook switch HS and cut-off circuit CF are provided between line terminals L1/L2 and talking circuit TEL.

Gate circuit NAND2 makes pass output (a) after restart of the clocking action and sends the previous notice of the talking end to the telephone receiver via oscillator OSC for the period from the restart of clocking to generation of the output of NAND2. On the other hand, gate circuit NAND3 makes pass count output (b) after the restart of clocking at CUT and cuts off circuit TEL by the output of NAND3. In such way, the constitution can be simplified at the exchange side, at the same time increasing the circuit using efficiency.
