The official website - Shenzhen Mingjiada Electronic Co., LTD
In high-end fields such as radar detection, energy monitoring and medical imaging, RMS-DC converters and precision modulators/demodulators act like the "nerve centers" of the signal chain, transforming the chaos of the analog world into precise decisions in the digital domain. However, device selection deviations, project terminations or technological iterations often leave these high-value chips in idle inventory, eroding the cash flow of enterprises. Shenzhen Mingjiada Electronics Co., Ltd. is driven by the dual wheel of "technology insight + global circulation" to build a closed loop of spot supply and recycling for ADI's full range of RMS-DC converters and modulators/modems, helping customers overcome signal processing bottlenecks while activating the secondary value of "dormant assets".
I. Core Products: The technical benchmark defining signal accuracy
1. Rps-dc Converter: The "Energy Translator" of the Real World
ADI's RMS-DC converter breaks through the limitations of traditional peak detection and directly measures the True RMS of the signal, achieving power metering with an error of less than 0.1% in complex waveform scenarios. Mingjiada mainly supplies three types of products:
Wideband precision type: such as AD736/AD637, it supports a military temperature range of -55℃ to 125℃, with a frequency response coverage of 0 to 10 MHz. In 5G base station power amplifier monitoring, it can replace six discrete modules, increasing the efficiency of heat dissipation analysis by three times.
Low-power integration: Represented by ADL5511, the static current is as low as 350 μ A. It integrates A logarithmic amplifier and envelope detector, extending the battery life of wearable devices by 40%.
High-voltage isolation type: Equipped with ± 300V common-mode suppression circuit, it is used for phase monitoring in smart grids and can withstand IEC 61000-4-5 standard surge impacts, helping Schneider Electric compress fault diagnosis speed to the microsecond level.
2. Precision Modulator/Demodulator: The "Architect" of Spectrum Order
From software-defined radio to quantum communication, these devices deconstruct complex modulated signals (such as QAM and OFDM) through orthogonal demodulation (I/Q demodulation) technology. The supply matrix of Mingjiada includes:
The flagship analog modulator AD630: With a balanced modulation error of less than -60 dB, it has become a reference device for satellite communication payloads and achieved 1 Gbps zero-error transmission in SpaceX inter-satellite links.
Digital demodulation system-on-chip AD9361: Supports full frequency band programmability from 70 MHz to 6 GHz, integrates 12-bit ADC/DAC, and has been widely adopted by Huawei's 5G RF units, reducing the size of base stations by 50%.
Microwave demodulation module HMC694: The operating frequency band covers 24 to 44 GHz, with phase noise of -158 dBc/Hz (@100 kHz offset), enabling millimeter-wave radar to achieve an angular resolution of ±0.1°.
Ii. Supply Barriers of Mingjiada: The Integration of Original Factory Resources and Agile Delivery
Facing the normalization of global chip shortages, Mingjiada reshapes supply standards with "deep inventory + technology empowerment"
2 million model Super Stock Pool
The Shenzhen central warehouse always keeps over 5,000 pieces of popular models such as AD736 and AD630 in stock. Urgent orders will be dispatched within 24 hours. The Hong Kong bonded warehouse supports settlement in US dollars/euros, and orders from Europe and America can be delivered within 72 hours.
Original factory-level quality control system
All devices are provided with ADI batch traceability files. Through X-ray scanning and dynamic parameter testing at -40℃ to 125℃, the risk of refurbishment is completely eliminated (the recognition accuracy rate of refurbished chips is >99.9%).
Flexible procurement model
Support applications for R&D samples with a minimum order of one piece. The price reduction for orders of thousands of pieces can reach 15%. We will simultaneously launch an inventory recovery service, repurchasing unused components at 50% to 75% of the new product price in cash to alleviate customers' financial pressure.
Iii. Closed-loop Service: Value Reengineering in the Technology Life Cycle
Mingjiada innovatively integrates the "supply - recycling" dual channels to solve the problem of resource mismatch in the electronics industry
High-price purchase of idle inventory
For discontinued models (such as AD636) and scarce components (ADF4158 supporting LVDS interface), a premium of up to 45% is provided based on global supply and demand data. Devices that have undergone triple quality inspection enter the redistribution network, with a reuse rate of over 95%.
ESG compliance disposal
Chips that fail to meet performance standards are disassembled by halogen-free pyrolysis technology, with a precious metal recovery rate of ≥95%. For every 100,000 ADI chips processed, 1.2 tons of electronic waste are reduced, helping enterprises achieve their carbon footprint goals.
Four-step Rapid monetization
Submit the list → 24-hour quotation → global insured logistics → inspection and T+1 payment. The entire process is compressed to 5 working days, which is three times faster than the industry average.
