Description: A、Technical indicators 1、Long88mmWidth58mmHigh25mm。2、Power supply voltage：12VDC，Current is less50mA。3、Gain：30MHz-1GHzFrequency band greater29dB。4、The input/output impedance：50Ohm5、Maximum output power：10dBm6、 Input signal：<=-30dBm7、Bandwidth：9KHzTo3GHz(Gain varies with different frequencies)8、The measured gain： F=8KHz GAIN=21dB F=9KHz GAIN=24dB F=50KHz GAIN=30dB F=1MHz GAIN=30dB F=5MHz GAIN=31dB F=20MHz GAIN=33dB F=35.0MHz GAIN=34.03dB F=1GHz GAIN=33.08dB F=1.5GHz GAIN=25.62dB F=2.5GHz GAIN=13.00dB F=3GHz GAIN=9.21dB The signal source string40dBThe attenuator after，Received the measured input from the spectrum analyzer30MHz-1GHzThe spectrogram，It can be seen that the gain fluctuation is very small，Less±2dB。 The signal source string40dBThe attenuator after，Received the measured input from the spectrum analyzer30MHz-3GHzThe spectrogram。 Enter the magnetic field probe，Amplifier as well as practical results。 8. Noise figure（The theoretical value） 300MHzWhen，NFAbout1.8dB 1GHzWhen，NFAbout2.3dB 2GHzWhen，NFAbout3.0dB 3GHzWhen，NFAbout3.6dB II、WithSR_RFamp002The comparison1. SR_RFamp002The gain ratioSR_RFamp001Low。2. SR_RFamp002The noise figure of the superiorSR_RFamp001。3. My advice： When the sensor's own gain is relatively high or the dynamic range of the spectrum analyzer is relatively wide， Choose the one with small noise coefficientSR_RFamp002。 For example：Using near-field probe、Bipolar antennas，WithSR_RFamp001Effect is good；When using an antenna with higher gain such as logarithmic period，SR_RFamp002Effect is good。 Three、Performance ComparisonBecause there is no special instrument for measuring amplifier on hand，So the analogy method is adopted。1. The noise floor comparison (The amplifier input floating)A treasure on“low-noise output LNA（Gain 32dB）”The noise floor of the figure： SR-Rfamp001（The low-noise amplifier）The noise floor of the figure： It is evident that，It's better than the one on a treasure“low-noise output LNA（Gain 32dB）”The background noise is much lower，Compare the two pictures above，The noise floor at least low10dBMore。 Personally, I think，OnEMCRectification，The noise level of the amplifier itself is crucial.，BecauseDUTThe generated clutter is often submerged in the noise，Reduce the noise level of the amplifier，Actually improves the signal-to-noise ratio (SNR)，To makeDUTThe clutter emitted is easier to be observed by us.。 2. The actual acquisition spectrum comparison（The spectrum analyzer input pick upΦ2cmThe near-field magnetic probe）A treasure on“low-noise output LNA（Gain 32dB）”The measured spectrum： SR-Rfamp001（The low-noise amplifier）The measured spectrum： It is evident that，The low-noise amplifierThe measured spectrum is much cleaner。 Four、Using the present invention Special reminder： 1. Well connected to all signal lines，First spectrometer power，Give amplifier power。 2. Amplifier does not support hot-swap，Please do not pull and plug signal lines with electricity，To prevent static electricity or electric leakage from damaging the amplifier。 Payment We accept PayPal only.We only ship item to your PayPal verified address.Payment must be received within 3 days from the date of purchase.Orders will be processed and dispatched within 3 days normally Terms Of Sales 1.
