2 LXY28161 Specification
2 LXY28161 Specification

... LXY28161 are designed to operate with VDS ranging from 0.4V to 0.8V (depending on IOUT=5 ~ 60mA), considering the package power dissipating limits. VDS may be higher enough to make when VLED=5V, PD (act) < PD (max) when VLED=5V and VDS=VLED–VF, in which VLED is the load supply voltage. In this case, ...

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.
