WARNING:

Never connect the output of the TBLPA1 directly to the input of a spectrum analyzer. Check the maximum input ratings of the spectrum analyzer and protect it with an appropriate attenuator. Open or shorted load is not recommended, potentially can cause damage.

Example:

Rigol DSA815 – maximum input power rating: +20dBm
