The following are Extracts from HackRF Documentation that can be found here.. This applies to all Transmissions using the HackRF/ PortaPack.
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.
- 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.
- 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.
What gain controls are provided by HackRF?
HackRF provides two TX gain controls are LNA (I) (0 to 47 dB in 1 dB steps) and RF AMP (0 or 14 dB)
Use of HackRF
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.Note there are no Filters in the HackRF to limit spurious transmissions and this must be provided by external circuitry.
WARNING
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.
