Description: for HackRF One hardware mainly consists of the following parts 1. RFFC5072: The mixer provides local oscillator from 80MHz to 4200MHz 2. MAX2837: 2.3GHz to 2.7GHz wireless broadband RF transceiver 3. MAX5864: ADC/DAC, 22MHZ sampling rate 8bit 4. LPC4320/4330: ARM Cortex M4 processor clocked at 204MHZ 5. Si5351B: I2C programmable arbitrary CMOS clock generator, providing 40MHZ 50MHZ and sampling clock by 800MHz frequency division 6. MGA-81563: 0.1-6GHz 3V14 dBm amplifier 7. SKY13317: 20 MHZ-6.0 GHz RF single pole three throw (SP3T) switch 8. SKY13350: 0.01-6.0 GHz RF single pole double throw (SPDT) switch Taking the receiving process as an example, the process after the signal enters from the antenna is as follows 1. The RF switch determines whether to amplify through a 14dB amplifier 2. High-pass or low-pass filter the signal through the image suppression filter 3. The signal is mixed by the RFFC5072 chip to a fixed intermediate frequency of 2.6GHz. 4. The latest firmware supports the option of variable IF 5
