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 <https://greatscottgadgets.com/2015/05-15-hackrf-one-at-1-mhz/>`__)
* 10 MHz to 2150 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increases
* 2150 MHz to 2750 MHz: 13 dBm to 15 dBm
* 2750 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increases
* 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 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. 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.
