Shulou(Shulou.com)11/24 Report--

CTOnews.com November 10 news, according to Hangzhou Geocore Technology Co., Ltd. (hereinafter referred to as: geocore Technology) official news, November 10, geocore technology new products conference held smoothly in Shenzhen, launched the ultra-wideband, low-power, high-performance, highly integrated, and support Sub 6G software radio SDR RF transceiver-fashion series, has now completed mass production.

According to the introduction, the popular series of RF transceivers are completely independent innovation products of geocore technology, including dozens of Sino-US cutting-edge patent technologies, which can be widely used in almost all modern digital wireless communication systems, such as general software radio system, 5G / 4G and private network wireless communication base stations, multi-function intelligent terminals, peer-to-peer communication systems, etc. According to the introduction, ▲ series RF transceivers are completely independent innovation products of Geocore technology.

CTOnews.com learned that the popular series of chips can support the frequency range of 30MHz-6GHz, support ultra-wide and ultra-narrow bandwidth requirements, and configurable RF bandwidth can support the range from 12KHz to 100MHz. At the same time, it also integrates 12bit's analog-to-digital converter ADC and 12bit's digital-to-analog converter DAC, built-in programmable analog filter, analog low-pass filter supporting minimum 0.7MHz bandwidth, analog low-pass filter with TX maximum 50MHz bandwidth, and analog low-pass filter with RX maximum 50MHz. The mixer and phase-locked loop are also integrated in the chip, and the transmitter part is integrated with a driver-level amplifier, which can output single-tone signals above 8dBm.

▲ figure from the Earth Core Technology Wechat popular series RF transceivers use direct frequency conversion architecture, with ultra-low power consumption, high modulation accuracy, low-noise excellent performance, power consumption is only a single channel 500mW. The product has the functions of image suppression calibration, local oscillator leakage calibration, transmit power monitoring, spurious suppression and receiver channel gain calibration, supports TDD and FDD systems, supports multi-chip usage scenarios such as MIMO, and can be widely used in traditional base stations, special radio stations, microwave relays, micro base stations, aerospace, satellite, radar, vehicle networking and other application scenarios.

The popular series adopts the mainstream 10mm × 10mm, 144pin chip-level ball grid array package (CSP_BGA), and the chip register read and write control adopts the standard four-wire SPI. The analog RF power supply is mainly 1.3V, and the digital interface power supply is 3.3V or 2.5V.
