... CANopen protocol for communication. The electrical interface is a TJA1050 high-speed CAN transceiver. Before connecting Accelnet Micro Module to the CAN network, it must be assigned a CAN address. This can be done via the RS-232 port, or by using logic inputs for the CAN address bits. The CAN addres ...

... An additional measure to prevent the unwanted turn-on is shorting the gate to emitter path. This can be achieved by an additional transistor between gate and emitter. This “switch” shorts the gate-emitter region after a time delay, as long as the driver shows a 0V signal at its output. The Schottky ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
