4082BF Datasheet
4082BF Price The video output of the K devices is a train of N charge pulses flowing onto the video recharge line and dummy re- charge line capacitances during each scan, with timing as shown in Figure 7. The pulses on the dummy line contain switching transients only; those on the video line contain switching transients plus the video signal. An output cIrcuit is required which is capable of diffarentially amplifying these pulses to a useable voltage level. 4082BF on stock a ) a D r - g 8 8 0 8 0 7 7 , o o o O O d _ U I o V 1 1 l L E S a E I I - M A W O N The q denotes specifications which apply over the specified operating temperature range. Note l: See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (17W for the LT1587-1.5 in T package). Power DESCRIPTION The RA30H4047M is a 30-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 400- to 470-MHz range. The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage (VGG=OV), only a small leakage current flows into the drain and the RF input signal attenuates up t0 60 dB. The output power and drain current increase as the gate voltage increases. With a gate voltage around 4V (minimum), output power and drain current increases substantially. The nominal output power becomes available at 4.5V (typical) and 5V (maximum). At VGG=5V, the typical gate current is l mA. This module is designed for non-linear FM modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate voltage and controlling the output power with the input power. |
