Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the precise signal chains of 5G communication, medical imaging and radar systems, the variable gain amplifier (VGA) has become the core component for front-end signal conditioning due to its wide dynamic range and precisely adjustable gain. However, project termination, design changes or excessive material preparation often lead to a large backlog of brand-new and unused ADI VGA chips for enterprises, occupying valuable cash flow. Shenzhen Mingjiada Electronics Co., LTD., relying on ten years of ADI product technology accumulation and the premium model of globally scarce models, specializes in high-price recycling of original and brand-new VGA chips from ADI, providing enterprises with one-stop solutions for inventory monetization and resource recycling.

Variable gain amplifiers (VGA) are used in a variety of remote detection and communication devices. It can provide excellent performance for signal chains that require a high dynamic range. Applications ranging from ultrasonic waves, radar, lidar, wireless communication to voice analysis all utilize VGA to provide outstanding performance.

Mingjiada's core recycled VGA products

Baseband programmable VGA filter

ADI's RF VGA, IF VGA and variable gain control products provide high performance required for communication, instrumentation and military design. This product series includes continuous analog linear dB products based on the X-AMP® interpolation architecture, as well as digital step control products that provide 0.25dB precision step and linear voltage digital control functions. Moreover, the ADI RF VGA has a high degree of integration. It integrates a digitally controlled multi-pole analog filter and an AGC circuit that supports automatic level control on the chip.

Programmable gain amplifier

ADI's programmable gain amplifiers (PGA) feature outstanding gain accuracy, inter-channel matching specifications, and a low drift of 1 ppm/°C. The gain can be set within the range of 1 V/V to over 4000 V/V by using a simple serial or parallel interface.

Analog control variable Gain Amplifier (VGA)

ADI's voltage-controlled variable gain amplifier (VGA) can provide continuous gain control for various audio and optical frequency bands over a wide dynamic range. ADI's VGA enables users to adjust the signal amplitude in real time, thereby improving the dynamic range of the circuit. This is crucial for applications related to ultrasonic, voice analysis, radar, wireless communication, and instrumentation, all of which typically use analog control VGA.

Digital control VGA

ADI's digital control variable gain amplifiers can provide discrete-level gain control over a fixed number of control bits for various audio and optical frequency bands. ADI's VGA improves the dynamic range of the circuit by allowing users to adjust the signal amplitude in real time, which is crucial for a wide range of applications involving ultrasonic waves, voice analysis, radar, wireless communication and instrumentation.
