Ultra-wideband low-noise amplifier MICROWAVE

摘要

The invention relates to the field of electronics and is used in the input circuits of receivers, of radio telecommunication devices and microwave frequencies, and also in the antenna systems to compensate for losses in the coaxial paths. The main technical problem is to provide a device having a frequency response increases with increasing frequency with a pronounced rise in the upper frequencies with the possibility of adjustment, which improves the overall system transmission coefficient of the device, wherein the utility model is applied. The apparatus comprises a housing in which the amplifier stages are arranged one with the coupling capacitor 2. The amplification stages are performed one FET. The electric circuit device between the coupling capacitor 2 amplifier stages 1 introduced equalizer frequency response 3 formed on a microstrip circuit board to form a U-shaped resistive attenuator comprising a series resistor 4 and shunt resistors 5. Shunt resistors attenuator 5 connected to a microstrip transmission line with via the inductance elements 6, made in the form of wire segments. 2 yl.
