Application Information
The B-AMP 12 can be used to amplify a
signal ≤ 13 dBm (or 1 Vrms at 50 Ω) in the frequency range
from DC to 50 MHz.
The amplification factor of B-AMP 12 is 12 dB (or factor 4). Output impedance and input impedance of
B-AMP 12 are
50 Ω.
Typical applications:
1. Gain measurements
B-AMP 12 can be used to increase the signal level during a gain measurement or an
S21 transmission measurement.
2. Impedance measurements
B-AMP 12 can be used to measure impedance with higher AC signal levels.
Figure 4-1 shows a typical setup where B-AMP 12 is used to amplify the output signal of the Bode 100
vector network analyzer to measure S21 of a 2-port DUT using up to 25 dBm signal level.
Figure 4-2 shows a typical setup using the B-AMP 12 to measure impedance of a one-port DUT with up
to 25 dBm AC signal level.
Note:
This setup requires Open, Short and Load calibration at the DUT port.

NOTICE
► Make sure that the DUT can withstand the 25 dBm output level of B-AMP 12
► Be aware that B-AMP 12 does not indicate if the output is active or not
