Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Today, with the rapid development in the fields of communication, medical care and industrial automation, the variable gain amplifier (VGA), as a key component in the signal chain, its performance directly affects the system accuracy and response speed. However, with the upgrading of 5.5G technology and the acceleration of equipment iteration, many enterprises are facing the problem of overstocking of brand-new original ADI VGA chips - these high-value devices occupy valuable cash flow but are idle due to technological iteration.

Shenzhen Mingjiada Electronics Co., LTD., relying on over a decade of experience in the field of electronic component recycling, has launched a dedicated high-price recycling service for ADI variable gain amplifiers (VGA). Through professional assessment, rapid monetization, and a green circular model, it helps enterprises revitalize asset value and accelerate capital turnover.

Core recycling scope

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.

2. 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.

3. 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.

4. 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.

The core advantage of Mingjiada's recycling service

Facing the challenge of intensified fluctuations in the global semiconductor supply chain, Mingjiada Electronics has built three core capabilities to provide differentiated value for ADI VGA recycling.

1. Professional assessment

Mingjiada adopts a triple quality inspection process: verifying the integrity of the internal structure through X-ray inspection, confirming the authenticity of the device by comparing the original factory code, and conducting electrical performance tests (including key parameters such as gain range, linearity, and noise figure) to ensure that the functions meet the standards.

2. Transparent prices

Based on real-time global supply and demand data, Mingjiada offers competitive quotations that are 5% to 15% higher than the market average, especially providing a higher premium space for discontinued and scarce models (such as AD8330).

3. Global network and rapid delivery

Relying on its warehousing centers in Shenzhen, Hong Kong, North America and Europe, Mingjiada achieves efficient cross-regional inventory allocation. We support global cash on delivery logistics (DHL/UPS/ SF Express) and local customs clearance services. From submitting the list to inspection and payment, it only takes 5 working days at the fastest.

In response to urgent capital demands, Mingjiada also offers an expedited assessment channel, completing the inspection and payment within 48 hours, significantly shortening the enterprise's capital recovery cycle.

Recycling process

List submission

Customers only need to organize the inventory information of ADI VGA, including model (e.g. AD604, AD8334, etc.), quantity, form of package (SOIC, LFCSP, etc.) and batch code, and submit it to the evaluation team via email (sales@hkmjd.com) or the official website.

Professional assessment

The technical team will complete the model identification and market value analysis within 24 hours, and provide feedback on the testing plan and estimated quotation. For high-value models, sample delivery verification is supported to ensure the accuracy and reliability of the assessment results.

Logistics delivery

Mingjiada offers full insured transportation services and supports global door-to-door pickup or cash on delivery. Relying on the service network covering Japan, Hong Kong, the United States, Germany and other places, achieve efficient and safe cross-border logistics.

Acceptance and payment

Mingjiada promises to complete the payment within T+1 working day after the goods are inspected and found to be correct. It supports settlement in multiple currencies such as US dollars, euros, and RMB. From the submission of the list to the arrival of funds, the entire process takes no more than five working days, significantly alleviating the cash flow pressure on enterprises.

Whether you are a component distributor, equipment manufacturer or R&D institution, simply send your inventory of ADI VGA to sales@hkmjd.com and our professional team will provide you with a recycling solution at a price higher than the market average within 24 hours.
