摘要： A semiconductor device having two PIN-diodes arranged in series and in opposition, in which the semiconductor body comprises two surface zones of a first conductivity type which extend in a high-ohmic surface layer, said surface layer separating the surface zones from one another and from a low-ohmic region of the second conductivity type. The surface zones and the low-ohmic region are contacted at the same surface of the semiconductor body, preferably by means of beam leads. The device is particularly suitable for high frequency applications and may form part of an integrated circuit.

摘要： A phase comparing circuit in which four diodes constituting a bridge circuit which operates as a signal gate circuit and is supplied with an input signal to and delivers an output signal from a pair of opposite junctions of the bridge circuit. The signal gate circuit is controlled by a pair of constant current switching devices connected to another pair of junctions of the bridge circuit and the control switching devices are controlled by a control signal such that the absolute value of the output current is maintained constant regardless of the value of the input signal, and the output signal is obtained across a capacitor as a phase compared signal between the input signal and the control signal.

摘要： A device for supplying current to a load from a relatively wide range of D.C. and A.C. voltage sources, and affording time delayOFF mode of deenergization upon opening of a selector switch. An electric illuminous indicating device provides indication of steady state and time delay-OFF modes of operation by steady and blinking illumination conditions. Provision is made to prevent improper operation of the device when the leakage current resistance shunting the open selector switch circuit exceeds, for example, 40,000 ohms. Unwanted operation due to transient voltage and current conditions is provided by extensive use of suppression and blocking devices.

摘要： An improved gate circuit for sampling the amplitude of high frequency signals. The circuit is provided with a shunt element and/or a diode for conducting the gate pulses so as to apply the gate pulses to the connecting point between diodes of a series circuit connected between an output terminal and the high frequency signal, thereby preventing the distortion of the waveform originated by the reflection of the measuring signal. Also disclosed is an improved circuit wherein a capacitor having a value of at least 300 pf is coupled from a point of the series circuit to ground, thereby preventing a leakage signal from appearing at the output terminal. These combined improvements yield better high frequency characteristics for the gate circuit.

摘要： A matched filter for use in a bit-by-bit digital detection circuit is shown including a pair of inductors through one of which current including signal and noise flows during a particular bit period. At the end of that bit period the circuit is interrupted by a hot carrier diode and the resulting voltage pulse having a particular polarity and magnitude is passed through a second hot carrier diode which is turned on when the first hot carrier diode is turned off. The second hot carrier diode is immediately turned off after the pulse transient has been threshold detected. At the time of turning off the first hot carrier diode and the current charge therein dumped, signal current flows in the second inductor by the turning on of a hot carrier diode. At the end of the second bit period, the integrated current in the second inductor is interrupted by a further diode switch is momentarily turned on and then off. The polarity and magnitude of the second transient pulse is converted into the proper data pulse and while the current charge in this inductor is being dumped, the first inductor is again on and is receiving the current for the third pulse. That is, there is no need for a zero interval between data pulses because the current of one inductor is being processed and dumped while the other inductor is being charged with the new data current and so on.

摘要： A network for gating a signal to be transmitted across a pair of terminals is connected in parallel across the terminals. The network includes a pair of diodes connected in parallel and oppositely poled which may be biased into conduction when attenuation is desired and into nonconduction when no attenuation is desired. A feedback amplifier is employed to hold the bias voltage for one of the diodes equal and opposite to the bias voltage for the other diode. A resistor-capacitor network allows the bias voltage on the diodes to be varied gradually between the off and on conditions of the gating circuit.

摘要： A voltage-controlled attenuation circuit providing an approximate linear relationship between a control voltage and the logarithm of the circuit attenuation ratio. The circuit includes parallel diode voltage dividers connected in parallel with a signal source and a source of control voltage which drives two pairs of current bias sources. The signal current adds to and subtracts from the bias current in each of the voltage dividers to yield a logarithmic voltage output across the summing resistors forming an output circuit across the pair of voltage dividers.
