Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Ltd (hereinafter referred to as "Geocore"), a new product launch event was successfully held in Shenzhen on November 10, which announced the Fengxing series of SDR RF transceivers with ultra-broadband, low power consumption, high performance, high integration and support for Sub 6G software radio.

According to the introduction, Fengxing series RF transceiver is a completely independent innovative product of Geocentric Technology, which contains dozens of cutting-edge Chinese and US patents and can be widely used in almost all modern digital wireless communication systems, such as general-purpose software radio systems, 5G / 4G and private network wireless communication base stations, multi-functional smart terminals, peer-to-peer communication systems, etc.

The Windstream family of chips can support a frequency range of 30MHz-6GHz, supporting both ultra-wide and ultra-narrow bandwidth requirements, with configurable RF bandwidths ranging from 12KHz to 100MHz. A 12bit analogue-to-digital converter ADC and a 12bit digital-to-analogue converter DAC are also integrated, with built-in programmable analogue filters, supporting analogue low-pass filters with a minimum bandwidth of 0.7MHz as well as analogue low-pass filters with a maximum bandwidth of 50MHz for TX and 50MHz for RX. The mixer and phase lock loop are also integrated inside the chip and the transmit section has an integrated driver stage amplifier that can output single tone signals above 8dBm.

The Windy series RF transceiver adopts direct frequency conversion architecture, with ultra-low power consumption, high modulation accuracy, low noise and only 500mW power consumption for a single channel. It can be widely used in traditional base stations, dedicated radios, microwave relay, micro base stations, aerospace, satellite, radar, Telematics and other applications.

The Windstream series adopts the industry's mainstream 10mm x 10mm, 144-pin chip-level ball grid array package (CSP_BGA), and the chip register read/write control adopts standard four-wire SPI.
