Preamplifier (Low Noise Amplifier) Selection Guide
Preamplifier (Low Noise Amplifier) Selection Guide
Definitions
Frequency - is the range the preamplifier with work over and where the specification is given are measured and guaranteed. Small margins outside the frequency band may be usable, but parameters are no longer guaranteed and should be used.
Gain – is the increase in dB expected of the test signal. This number is usually given as a minimum. With delivery, a gain curve and data table are provided as this changes over the frequency range.
N.F. (Noise Figure) – is the overall Noise the amplifier will generate. A preamplifier increases the “noise” seen on your receiver. A smaller N.F. is better. This is an important specification as any added noise reduces the overall effectiveness of the added gain. This number is given in a generic dB rating and, depending on your measurement resolution bandwidth (RBW), will determine the actual dB loss in sensitivity of the receiver’s noise floor.
P1dB – is the power level where the amplifier starts to saturate. At higher output levels, the amplifier should not be used as gain error becomes an issue. Above the p1dB level, the amplifier produces harmonics and possible intermodulation. These intermodulations signals are not real and may mislead the user to troubleshoot “ghost” signals. This value also shows the overall dynamic range of the amplifier. A higher value is better.

Use preamplifier to:
- Compensate for Cables losses at high frequencies
- Compensate for high antenna factors
- Increase the sensitivity of receivers and spectrum analyzers
- Read smaller RF and Microwave signals
- Increase your usable dynamic range
- Place near the measurement instrumentation or close to the antenna
