FMAM1045

RF Amplifiers Overview

The FMAM1045 is a low noise amplifier manufactured by Fairview Microwave. It operates within a frequency range of 1 MHz to 500 MHz and provides a gain of 33.5 dB. The device features a noise figure of 2 dB, a 1 dB compression point (P1dB) of 13 dBm, and an output third-order intercept point (OIP3) of 25 dBm. It requires an operating supply voltage between 11 V and 30 V with a current draw of 40 mA. The unit utilizes SMA connectors for input and output interfaces.

RF Amplifiers Feature Summary

• Provides high signal amplification with a fixed gain of 33.5 dB across the specified bandwidth
• Maintains low signal degradation with a noise figure of 2 dB
• Operates effectively from DC up to 500 MHz using standard SMA interfaces

RF Amplifiers Applications

• Low noise signal amplification in RF receiver chains
• Test and measurement equipment requiring stable gain at lower frequencies
• Communication systems operating within the 1 MHz to 500 MHz spectrum

RF Amplifiers Procurement Notes

Verify the specific datasheet revision and connector type compatibility before integration. Confirm that the power supply voltage remains within the 11 V to 30 V range to ensure proper operation. Check for any RoHS compliance documentation if required for your manufacturing process. Ensure SMA mating cycles are respected to maintain signal integrity over time.

RF Amplifiers Selection Notes

Select this component when a moderate gain of 33.5 dB is required alongside a low noise figure of 2 dB. It is suitable for applications where the frequency range extends down to 1 MHz. Compare its P1dB of 13 dBm against system linearity requirements. Consider the 40 mA current consumption for power budget calculations in portable or battery-operated designs.
