Professional External Power Amplifier for Vector Network Analysis
The OMICRON Lab B-AMP 12 is a precision external power amplifier designed specifically for use with the Bode 100 vector network analyser. This professional-grade amplifier delivers a consistent 12 dB gain (×4 amplification) across the entire DC to 50 MHz frequency range, enabling high-power measurements up to 25 dBm output level.
High-Performance 50Ω System Design
Built around a true 50Ω input and output impedance design, the B-AMP 12 provides excellent return loss performance (>30 dB) ensuring minimal signal reflections and accurate measurements. The amplifier features dedicated impedance measurement ports (CH1 and CH2) that provide defined attenuation levels for direct impedance measurements at high signal levels.
| Frequency Range | DC – 50 MHz |
| Gain | 12 dB ±0.25 dB |

Wiring Quick-Start
Connect the B-AMP 12 between your Bode 100 output and device under test:
Advanced Measurement Capabilities
The integrated CH1 and CH2 measurement ports provide calibrated signal paths for impedance analysis:
| Input to CH1 attenuation | 14.5 dB typ. |
| Input to CH2 attenuation | 20.8 dB typ. |
| Output to CH2 voltage gain | -33 dB (×0.022) |
| CH1/CH2 return loss | >25 dB |
These measurement ports enable direct impedance measurements with high AC signal levels, essential for characterising voltage-dependent components like chip capacitors and varactors.
