RX888 ADC SDR Receiver Radio 1KHz-1.8GHz 16Bit Direct Sampling 32Mhz HF UHF VHF USB3.0 HDSDR

Description RX888 direct sampling 16bit SDR receiver maximum 64M real time bandwidth VHF UHF support up to 1 8GHz maximum real time bandwidth 8M USB3 0 connected to a computer for use Through the optimization of proprietary software and firmware the requirements for computer performance have been greatly reduced Re optimize the design of pcb the clock and phase locked loop are shielded independently by shielding cover The spectrum is clean and there is no local oscillator interference Looking at the frequency spectrum of the last picture it is clear whether there is spurious interference at a glance All use LDO power supply the whole machine 7 LDO power supply linear power supply eliminates the interference caused by DCDC It uses a large vacuum KDS VCXO crystal oscillator and is designed with a potentiometer to fine tune the frequency deviation It is not a cheap ordinary crystal as a clock Adding a 20dB differential low noise amplification LNA to the ADC front end can effectively improve the medium wave sensitivity and improve the receiving performance under the small sized antenna The re adjusted shortwave LPF low pass filter the bandwidth is adjusted to 64M and the latest proprietary software supports direct sampling of shortwave 64M Software extio dll redesign excellent UI and rich setting items support HF and VHF UHF antenna bias power supply BIAS T switch HF three gears 0db 10db 20db attenuation ATT and VHF LNA And VGA settings support global band
