Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the race and iteration of 5G base stations, millimeter-wave radars and space communications, the phase-locked loop (PLL) frequency synthesizer, as the "space-time commander" of signal generation, its phase noise and frequency stability directly determine the performance boundary of the system. Shenzhen Mingjiada Electronics Co., LTD., with nearly 30 years of industry experience, has established a full life cycle service system for ADI phase-locked loops, covering supply, selection and recycling, providing core support for high-frequency and precision applications to global customers.

I. Core Categories: Covering the ADI PLL matrix in all scenarios

Mingjiada Electronics supplies four major categories of ADI PLL products to meet the demanding requirements ranging from ground communication to deep space exploration:

Phase-locked loop with integrated VCO: Supports up to 13.6 GHz frequency band, narrowband/wideband design with integrated voltage-controlled oscillator (VCO), providing ultra-low phase noise clock sources for 5G base station local oscillators and satellite payloads, with phase noise accuracy up to -110 DBC /Hz (@100 KHZ offset).

Fractional N frequency division PLL: It achieves sub-hertz frequency resolution through fractional frequency division technology, solving the frequency point conflict problem in LTE carrier aggregation. Typical models such as ADF4377 reduce signal distortion by 40% in Huawei's 64-channel Massive MIMO.

Integer N frequency division PLL: 18 GHz ultra-high frequency supports millimeter-wave radar frequency modulation. Devices such as ADF5610 achieve ±0.1° Angle measurement accuracy in vehicle-mounted corner radars. The installation volume in vehicles is expected to exceed 2 million pieces in 2024.

Conversion loop (offset loop) : It adopts a System-in-package (SiP) integrated isolation circuit, with a stray component attenuation of up to 60dB, replacing the traditional 6-module discrete design and helping ZTE reduce the size of base stations by 52%.

Ii. Service Advantages: Dual guarantees of direct supply from the original factory and rapid response

Mingjiada reshapes the service standards of the PLL market with the dual engines of "technology + supply chain"

Massive inventory and lightning-fast delivery

With over 2 million models in stock, covering industrial grade (-40℃ to 85℃) to military grade (ADF4372), urgent orders can be delivered globally within 48 hours. Cross-border customs clearance bottlenecks can be resolved through bonded warehouses in Hong Kong and Hungary.

Original factory genuine product guarantee

Original factory channel procurement ensures that every PLL chip comes from ADI's original factory or authorized channels, eliminating the risks of refurbishment and counterfeiting.

Green circular economy closed loop

Innovatively integrating the "supply - recycling" dual channels, we purchase idle PLL inventory at high prices (such as the discontinued model ADF4360). Through triple quality inspection including X-ray scanning and temperature chamber testing (-40℃ to 125℃), the device reuse rate reaches 95%, and the premium space is as high as 45%.
