Mingjiada Electronics Supply ADI Satellite Communication Chips, Supply RF Front-End Chips

With the global low Earth orbit (LEO) satellite constellation entering a phase of large-scale development, satellite communications have expanded beyond specialised aerospace applications into diverse civilian and commercial scenarios. As the core ‘nerve endings’ of the system, satellite communication chips directly determine the stability, transmission efficiency, and integration level of communication links.

Shenzhen Mingjiada Electronics Co., Ltd. – with years of specialisation in electronic components – has established itself as a renowned one-stop supplier of satellite communication chips through its global sourcing channels and rigorous quality control systems. The company consistently supplies full product lines for multiple internationally recognised brands, covering 【ADI】Ku/K/Ka-band satellite communication RF chips, precisely tailored for low-Earth orbit satellite terminals, ground stations, phased array antennas and other applications. Concurrently, the company offers premium chip buyback services, establishing a dual-loop supply chain system integrating ‘supply + recycling’ to enhance industry cost efficiency and resource circularity.

ADI (Analog Devices): A global leader in RF chip solutions, its satellite communication RF chips cover the full Ku/K/Ka frequency bands. Their highly integrated design significantly simplifies system architecture, finding extensive application in next-generation LEO satellites, ground station terminals, and phased array antenna systems. ADI is one of the core brands supplied by Mingjiada Electronics for satellite communication chips.

RF Front-End Chips (Core Product Category)
As the core component for satellite communication signal transmission and reception, RF front-end chips encompass subcategories such as upconverters and quadrature demodulators. Responsible for signal frequency conversion and conditioning, they are pivotal in determining communication bandwidth and signal quality. Mingjiada Electronics primarily supplies the full range of ADI brand RF front-end chips, covering the complete spectrum from 10.7GHz to 31GHz.

ADI RF Front-End Chips (Core Bestsellers)
1. ADMV4530ACCZ (Ka-band Upconverter)
Core Technical Features: Highly integrated design incorporating an I/Q mixer, low-phase-noise fractional-N phase-locked loop (PLL), voltage-controlled oscillator (VCO), and internal frequency multiplier, eliminating the need for complex external frequency synthesis circuits.
Application Scenarios: High-throughput satellite (HTS) communication terminals, 5G millimetre-wave backhaul equipment, military satellite communication uplink.
2. ADMV4540ACCZ (K-band Orthogonal Demodulator)
Core Technical Features: Highly integrated frequency synthesiser; RF front-end incorporates dual low-noise amplifier (LNA) paths supporting antenna polarisation selection; Integrated programmable Butterworth low-pass filter (6th order, selectable corner frequencies: 125/250/500MHz) with variable gain amplifier (VGA) to effectively suppress out-of-band interference, reducing bandwidth and resolution requirements for downstream analogue-to-digital converters (ADCs);
Application scenarios: K-band satellite direct-to-home (DTH) broadcasting, satellite Internet of Things (IoT) terminals, aeronautical airborne communication systems.
3. ADMV4680ACDZ (Ku-band beamforming chip)
Core Technical Features: Single-chip integration of 4 T/R channels, common RF port, quad power divider/combiner network, and T/R switch to enable half-duplex beamforming; ultra-low power design with receive mode power consumption of just 78mW (noise figure 1.9dB @ 12.7GHz) and transmit mode power consumption of 108mW (P1dB=9.5dBm);
Application Scenarios: User terminals for LEO constellations such as SpaceX Starlink, VSAT satellite antennas, and active antenna units (AAUs) for 5G millimetre-wave small cells.
