Mingjiada Seeks to Purchase TI Radiation-Hardened RF ADCs/DACs Globally — Supporting X-Band Satellite and Radar Payload Design; Genuine Products in Stock Required
With the rapid development of low-Earth orbit satellite constellations, deep-space exploration, and high-reliability radar systems, space electronics equipment places stringent demands on the radiation resistance and RF direct-to-ADC performance of signal chain chips. Shenzhen Mingjiada Electronics Co., Ltd. (www.hkmjd.com), a global distributor with nearly three decades of experience in the electronic components supply chain, is urgently sourcing genuine, original Texas Instruments (TI) radiation-hardened RF analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) from customers worldwide. These components are primarily intended for high-end aerospace applications such as X-band satellite communication payloads, phased-array radars, and on-board telemetry systems.
Key Models and Product Specifications
This procurement focuses on TI data converters with Radiation Hardness Assurance (RHA) or Radiation-Hardened Enhanced (SEP) ratings, specifically including but not limited to the following models:
AFE7950-SP / AFE7950-SEP: 4-transmit, 6-receive RF sampling transceiver, integrating a 12 GSPS DAC and a 3 GSPS ADC, supporting direct sampling in the L, S, C, and X bands, with a TID rating of up to 100 krad(Si) and a single-electron-lockout (SEL) immunity threshold of 70 MeV·cm²/mg, suitable for high-density, multi-mission satellite payloads.
ADC12DJ5200-SP / ADC12DJ5200-SEP: 12-bit resolution, sampling rate of up to 10.4 GSPS in single-channel mode, 5.2 GSPS in dual-channel mode, analog input bandwidth exceeding 8 GHz, with a total dose tolerance of 300 krad (Si) and SEL immunity of 120 MeV·cm²/mg; these are ideal choices for X-band radar and broadband communication receive chains.
DAC39RF10-SEP: A 16-bit, dual-channel, 10.4 GSPS RF DAC supporting RF signal output up to 12 GHz. When paired with the ADC12DJ5200-SEP, it forms a complete 2T2R transceiver solution that, when combined with TI’s aerospace-grade clock and power modules, can cover a 5 GHz instantaneous bandwidth.
In addition, Mingjiada is sourcing TI’s space-grade complementary chips, including the LMX2694-SEP RF synthesizer, LMK04832-SEP clock jitter cleaner, and TRF0208-SEP/TRF0108-SEP active baluns, to meet customers’ needs for a complete signal chain.
Analysis of Aerospace Applications
In X-band satellite communication downlinks, these chips support a direct RF sampling architecture, eliminating the need for complex multi-stage frequency conversion. This significantly reduces system power consumption and weight while maintaining an instantaneous bandwidth of over 1,200 MHz, enabling real-time transmission of high-definition remote sensing imagery and high-speed scientific data. In spaceborne Synthetic Aperture Radar (SAR) and Electronic Intelligence (ELINT) systems, sampling rates of up to 10.4 GSPS ensure precise capture and reconstruction of wideband signals, while radiation-hardened designs guarantee long-term stable operation in high-energy particle environments such as the Van Allen radiation belts.
