Bundle of the most common broadband amplifiers:

TBWA2-20dB and -40dB gain for connecting near-field probes - now up to 6 GHz!
TBDA1/14dB and -28dB for amplifying signals from HF function generators for compatibility measurements.
These broadband amplifiers are typically connected between the near-field probe and the spectrum analyzer to increase the dynamic range of the measurement. The amplifiers are now specified up to 6 GHz (see characteristics in the data sheet).
