Maximum Input Power

The maximum input power of HackRF One is a crucial consideration to avoid damaging your device.
The maximum input power of HackRF One is -5 dBm, which is the safe limit to avoid permanent damage.
Exceeding this limit can result in serious consequences, including permanent damage to your device.
In theory, HackRF One can safely accept up to 10 dBm with the front-end RX amplifier disabled, but this is not recommended due to the risk of accidental amplifier enablement.
Using an external attenuator is a safer option than relying on software or user settings to prevent amplifier enablement.

Minimum Detectable Power
The minimum detectable power of a SDR platform like HackRF is a complex question that depends on many variables.
Any answer would be very specific to a particular application, making it difficult to provide a general answer.
To determine the minimum detectable power, you would need to measure it yourself in the specific application.
This is because even a minor software update can result in a significantly different answer.
HackRF's specifications include operating frequency range, maximum sample rate, and dynamic range in bits, which can give you an idea of its suitability for a given application.
However, testing is still required to finely measure performance in an application.
Selecting the right antenna, external amplifier, and/or external filter can significantly enhance performance in a specific application.
This is because these components can greatly affect the SDR's ability to detect weak signals.

Maximum Transmit Power
The HackRF One's maximum TX power varies by operating frequency, with some ranges having a more consistent output than others.
In the 1 MHz to 10 MHz range, the maximum TX power generally increases as frequency increases, ranging from 5 dBm to 15 dBm.
For most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm.
The frequency range with the best performance is 2170 MHz to 2740 MHz, where the output power is consistently high.

Here's a breakdown of the maximum TX power across different frequency ranges:
- 1 MHz to 10 MHz: 5 dBm to 15 dBm
- 10 MHz to 2170 MHz: 5 dBm to 15 dBm
- 2170 MHz to 2740 MHz: 13 dBm to 15 dBm
- 2740 MHz to 4000 MHz: 0 dBm to 5 dBm
- 4000 MHz to 6000 MHz: -10 dBm to 0 dBm
Keep in mind that even at the lower end of the power range, the HackRF One is still capable of performing over-the-air experiments at close range or driving an external amplifier.
