Description
What is a 433MHz LNA Amplifier UHF Low Noise Amplifier?
The 433MHz LNA Amplifier UHF Low Noise Amplifier model CTRF-LNA-AMP-0433-3522-SMA-K RF is a 380-480MHz UHF LNA Amplifier center frequency 433MHz LNA Low Noise Amplifier supplied by C&T RF Antennas Inc.
433MHz LNA Amplifier UHF Low Noise Amplifier Product use:
Front-end 433MHz low noise amplifier for 433MHz receiver, with ultra-low noise factor, and high RF gain. Very suitable for amateur radio receiver front-end amplification use.
A single-stage amplifier vs a multi-stage amplifier
The noise figure F of a multi-stage amplifier depends mainly on its pre-stage.
If F1, F2,…, Fn are the noise coefficients of each amplifier stage in turn, then the equation A1,…, An-1 is the power gain of each amplifier stage in turn.
The larger the gain A1 of the preamplifier, the smaller the effect of the subsequent stages on the total noise factor F.
The noise figure of a single-stage amplifier depends mainly on the active devices used and their operating conditions.
Most modern low-noise amplifiers use transistors, field-effect transistors.
Microwave low-noise amplifiers use variable capacitance diode parametric amplifiers, the noise temperature Tθ of room temperature parametric amplifiers can be less than a few tens of degrees (absolute temperature), and the cooling parametric amplifiers can be less than 20K.
Gallium arsenide field-effect transistor low-noise microwave amplifier has been increasingly widely used, its noise factor can be less than 2 dB.
