FMAM5108

Overview

The FMAM5108 is a temperature-compensated low noise amplifier manufactured by Fairview Microwave, designed for operation within the 26.5 GHz to 40 GHz frequency range. Constructed using GaAs technology, this RF amplifier delivers a typical gain of 39 dB with a minimum specification of 35 dB. It features a noise figure of approximately 7 dB and an input P1dB compression point of 18 dBm. The device operates on a supply voltage between 12 V and 15 V, drawing 400 mA of current. It utilizes SMA connectors and includes a heatsink for thermal management, functioning reliably across temperatures from -55°C to +85°C.

Feature Summary

• Temperature compensation ensures stable performance across varying environmental conditions
• High gain capability suitable for sensitive signal amplification in millimeter-wave applications
• Integrated heatsink design supports thermal dissipation during continuous operation

Applications

• Millimeter-wave communication systems requiring low noise amplification
