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.

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.
