What is the Transmit Power of HackRF?¶
HackRF One’s absolute maximum TX power varies by operating frequency:
- 1 MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this blog post)
- 10 MHz to 2170 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increases
- 2170 MHz to 2740 MHz: 13 dBm to 15 dBm
- 2740 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increases
- 4000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases
Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm. The frequency range with best performance is 2170 MHz to 2740 MHz.
Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.
Before you transmit, know your laws. HackRF One has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your HackRF One legally.
