150A EMC Probe Amplifier Description The 150A EMC probe amplifier is a low-noise, wide-bandwidth amplifier designed for use with the Beehive Electronics 100 series EMC probes. The 150A is typically placed between the EMC probe and the spectrum analyzer. Its high gain and low noise improve the system sensitivity dramatically. This higher sensitivity allows the user to widen the spectrum analyzer resolution bandwidth, resulting in faster sweeps and measurements. Depending on the model of spectrum analyzer used, sensitivity can be improved by 20 to 30 dB. Features High gain and low noise improves measurement sensitivity and speed. Wide bandwidth allows it to be used with all 100 series probes. RF input and output protected against ESD and DC power. AC power supply included. Standard 50 ohm inputs and outputs allow it to be used in any application requiring a low noise amplifier. 1 Beehive Electronics Tel: (707) 824-9206 info beehive-electronics.com rev. 1.0 8555 Lawrence Lane, Sebastopol CA 95472 Specifications Gain 32 dB Frequency Response 100 kHz to 6.0 GHz: +/- 1.5 dB 150A Gain, Typical Unit 150A Gain, Typical Unit, Logarithmic Frequency Axis 40 40 35 35 30 30 25 25 20 20 15 15 10 10 5 5 0 0 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 0.01 0.1 1 10 100 1000 10000 Frequency (MHz) Frequency (MHz) Fig 1: Typical frequency response Fig 2: Typical freq. response, log scale Noise Figure 5 dB typical, 100 kHz to 4.0 GHz 6 dB typical, 4.0 GHz to 6.0 GHz 150A Noise Figure, Typical Unit 7 6 5 4 3 2 1 0 0 1000 2000 3000 4000 5000 6000 7000 8000 Freq (MHz) Fig 3: Typical noise figure 2 Beehive Electronics Tel: (707) 824-9206 info beehive-electronics.com rev. 1.0 8555 Lawrence Lane, Sebastopol CA 95472 Gain (dB) NF (dB) Gain (dB)
