0.1MHz～2000MHz 32dB LNA RF広帯域低雑音増幅器モジュール 無線周波数広帯域増幅器

説明

This product is suitable for frequencies ranging from 0.1MHz to 2000MHz with a gain of 30dB. The amplifier has excellent gain flatness when operating at frequencies below 500MHz, and can be adjusted carefully to be less than 1dB. Low frequency results in high gain consistency.

Working voltage: DC 5V-12V

NF:4.2dB

Maximum input power:+23dB

Input impedance: 50 ohms

Typical gain: 20DB@1000MHZ

P1DB:+20.4dB IP3:38dBM

The lower limit of the operating frequency of this amplifier is limited by the input and output capacitance, which defaults to 0.1uF and can operate up to 0.1MHz; It is possible to increase the input and output capacitance appropriately to extend the lower frequency limit, for example, at 10uF, it can operate up to 5KHz. If detailed calculation is required, it is important to note that the input and output impedance is 50 ohms, calculate the required capacitance value, and enhance the decoupling and voltage stabilization of the power supply.

When powered by 5~8V, it can be used as a variable gain amplifier, and the gain increases with the increase of the power supply voltage.

At 8-10V, the low-frequency gain reaches 30dB, and the amplifier has a low noise figure and good stability.
