Description
800MHZ AD8368 Analog Linear-in-dB VGA Amplifier Controllable Gain Amplifier Radio Linear Amplifier with AGC Detector
Product Description
The AD8368 is a variable gain amplifier (VGA) with built-in analog linear-in-dB gain control that operates from low frequencies to 800 MHz. High-performance variable gain control is possible, resulting in excellent gain range, uniformity, and flatness. The -12 dB to +22 dB gain range can be precisely adjusted to 37.5 dB/N with minimal consistency error. The AD8368 has a nominal 3 dB bandwidth of 800 MHz, independent of the gain setting. At 140MHz and maximum gain, OIP3 is 33dBm. The output noise floor is -143dBm/Hz and the corresponding noise figure at maximum gain is 9.5 dB.

Installation Instructions

Module usage precautions

(1) The module is powered by dual power supply, and the voltage cannot exceed 5V. (2) The measured bandwidth of AD8368 single-stage can reach about 450MHz (-3dB). Under the maximum gain of 22dB, the band is very flat. If you choose to continue to amplify after the stage, the bandwidth can reach about 200MHz. (3) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply. (4) It is recommended to use a good wire for the output signal to input and output the signal, and use an oscilloscope to observe the effect. Poor contact or poor quality wire may cause signal attenuation or excessive noise.
