In theory, HackRF One can safely accept up to 10 dBm with the front-end RX amplifier disabled. Exceeding -5 dBm can result in permanent damage! The maximum RX power of HackRF One is -5 dBm. You are responsible for using your HackRF One legally. HackRF One has not been tested for compliance with regulations governing transmission of radio signals. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.īefore you transmit, know your laws. Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. The frequency range with best performance is 2150 MHz to 2750 MHz. Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm.
HackRF One’s absolute maximum TX power varies by operating frequency:ġ MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this blog post)ġ0 MHz to 2150 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increasesĢ750 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increasesĤ000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases RP-SMA connectors are most common on 2.4 GHz antennas and are popular on Wi-Fi equipment. If you connect an RP-SMA antenna to HackRF One, it will seem to connect snugly but won’t function at all because neither the male nor female side has a center pin. Some connectors that appear to be SMA are actually RP-SMA. This means that it can be used for other functions by custom firmware. The DFU button only invokes the bootloader during reset. While holding the DFU button, reset the HackRF One either by pressing and releasing the RESET button or by powering on the HackRF One. To invoke DFU mode: Press and hold the DFU button. This bootloader makes it possible to unbrick a HackRF One with damaged firmware because the ROM cannot be overwritten. The DFU button invokes a USB DFU bootloader located in the microcontroller’s ROM. This is a reboot that should result in a USB re-enumeration.
The RESET button resets the microcontroller. SMA female clock input and output for synchronization Software-controlled antenna port power (max 50 mA at 3.3 V) Interface: High Speed USB (with USB Micro-B connector) Supported sample rates: 2 Msps to 20 Msps (quadrature)
