380-480MHz UHF LNA Amplifier Low Noise Amplifier

Description

What is a 380-480MHz UHF LNA Amplifier Low Noise Amplifier?

The 380-480MHz UHF LNA Amplifier Low Noise Amplifier model CTRF-LNA-AMP-3848-3522-SMA-K RF is a 433MHz center frequency LNA Amplifier 380-480MHz UHF Low Noise Amplifier supplied by C&T RF Antennas Inc.

The amplifier transistor’s own noise consists of the following four components.

① Flicker noise, whose power spectral density increases as the frequency f decreases, so is also called 1/f noise or low-frequency noise.

This noise is larger when the frequency is very low, and this noise can be neglected when the frequency is higher (above several hundred Hz).

② Thermal noise of the base resistance rb’b and.

③ Scattered particle noise, the power spectral density of these two types of noise is basically independent of frequency.

④ Distribution noise, whose intensity is proportional to the square of F. When f is higher than the cutoff frequency of the transistor, this noise increases sharply.

For low frequency, especially the ultra-low frequency low-noise amplifier should be selected 1/f noise small transistor.

For medium and high-frequency amplification, the transistor should be used as high as possible so that its operating frequency range is located in the flat part of the noise coefficient-frequency curve.
Field-effect transistors do not have scattered particle noise.

At low frequencies, it is mainly flicker noise, and at higher frequencies, it is mainly thermal noise generated by channel resistance.

It is usually less noisy than that transistors and can be used in low-noise amplifiers at much higher frequencies.
