TSM1011 - STMicroelectronics

... Under start-up or short-circuit conditions the TSM1011 is not provided with a high enough supply voltage. This is due to the fact that the chip has its power supply line in common with the power supply line of the system. Therefore, the current limitation can only be ensured by the primary PWM modul ...

... To observe the dynamic photo-thermal effect we apply a sinusoidal voltage to EOM2. The power incident on C2 is thus modulated around an average value, as well as the light power absorbed by the mirrors, and a cavity length change is originated due to their non-zero thermal expansion coefficient.

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.
