摘要： An RF coupler implementable as an integrated circuit includes a first transmission line having a first line portion and a second line portion. A first end of the first transmission line is coupled to an input port for receiving an RF input signal. A second end of the first transmission line is coupled to an output port for providing an RF output signal. The RF coupler further includes a second transmission line formed between the first line portion and the second line portion such that magnetic field produced due to the RF input signal in the first line portion and the second line portion envelops the second transmission line. A first end of the second transmission line is configured as a coupled port for providing a coupled RF signal, and a second end of the second transmission line is coupled to a termination element to form an isolation port.

摘要： A low leakage logic circuit. The low leakage logic circuit includes a control circuit for logic circuit. The control circuit has a first transistor, a second transistor, a third transistor, a first diode, a first resistor and a second resistor. When the control circuit is ON, a first circuit path in the logic circuit is supplied with a first voltage from the source terminal of the third transistor. This voltage acts as a logic output and has the ability to source current at output terminal of the logic circuit. When the control circuit is OFF, a second circuit path in the logic circuit is supplied with a second voltage from the control circuit which is lower than the turn-on voltage of the second circuit path. This voltage is insufficient to turn ON the logic circuit, hence no current flows into the logic circuit.

摘要： A low-loss Radio Frequency (RF) switch for high-power RF signals. The RF switch includes a first-biasing circuit connected to a first transistor and a second-biasing circuit connected to a second transistor. The RF switch switches its output signal between a first input signal and a second input signal. The first transistor is in a conduction state and the second transistor is in a non-conduction state when the first input signal is to be conducted to the output signal. The first-biasing circuit biases the first transistor at a first voltage for increasing conduction of the first input signal and the second-biasing circuit biases the second transistor at a second voltage for decreasing conduction of the first input signal. Moreover, the second transistor is in a conduction state and the first transistor is in a non-conduction state when the second input signal is to be conducted to the output signal.

The leakage diode is matched to the trigger diode to shunt any leakage current from the trigger diode to ground.

摘要： A portable tube holder apparatus and tube loading method facilitates safe and rapid loading of tubes containing electronic components into a machine. The tube holder has a tube guide sized to receive a plurality of tubes and a support to selectively hold the tubes in that guide. The holder can be loaded with a relatively large number of tubes at a workstation area and then used to safely transport the tubes to the machine without risk of the components falling out of the tubes. The support, which is preferably slidable, permits all of the tubes in the guide to be readily released into the machine's feeding system, enabling fast loading of the machine and also minimizing down-time for machines that cannot run while being loaded. The portable tube holder preferably has an interface designed to facilitate alignment of the tube holder's guide with the feeding system guide in the machine.
