Item Type: Software Defined Radio Platform Net Weight: 60 g / 2.1 oz(approx.) Product Size: Approx. 118 x 75 x 11mm / 4.6 x 3 x 0.4in For HackRF One hardware is mainly composed of the following parts: RFFC5072: The mixer provides a local oscillator from 80MHz to 4200MHz MAX2837: 2.3GHz to 2.7GHz Wireless Broadband RF Transceiver MAXS864: ADC / DAC, 22MHz sampling rate 8bit LPC4320 / 4330: ARM Cortex M4 processor, clocked at 204MHz Si5351B: I2C programmable arbitrary CMOS clock generator, providing 40MHz50MHz and sampling clock by 800MHz frequency division MGA-81563: 0.1-6GHz 3V, 14dBm amplifier SKY13317: 20MHz-6.0 GHz RF single pole three throw (SP3T) on SKY13350: 0.01-6.0GHz RF single pole double throw (SPDT) switch Taking the receiving process as an example, the process after the signal enters through the antenna is as follows: 1. The RF switch determines whether the amplifier is amplified by a 14dB amplifier. 2. High-pass or low-pass filtering of the signal through the image suppression filter 3. Signal RFFC5072 chip mixing to 2.6GHz fixed IF a. The latest firmware supports the option of variable IF b. IF range 2.150GHz-2.750GHz 4. The signal is sent to the MAX2837 chip and mixed to the baseband to output a differential IQ signal. a. During the MAX2837 chip can limit the bandwidth of the signal 5. The MAX5864 chip digitizes the baseband signal and sends it to the CPLD and the microcontroller TODO FIXME 6. CPLD 7. LPC4320 / 4330 processor sends sampling data to computer via USB 8. Put the RFFC5072 and MAX2837 in a shield to protect them from external interference and other chips on the board, and try to prevent electrostatic breakdown of some chips 1 x Software Defined Radio Platform
