FMAM5105F

Overview

The FMAM5105F is a temperature-compensated low noise amplifier manufactured by Fairview Microwave. It operates within a frequency range of 4 GHz to 12 GHz and utilizes GaAs technology. The device provides a minimum gain of 35 dB with a typical gain of 39 dB and a noise figure of 4 dB. It features a 22 dBm P1dB compression point and requires an operating supply voltage between 12 V and 15 V, drawing 350 mA of current. The component is designed for SMD/SMT installation in an SMA package and functions reliably across temperatures from -55°C to +85°C.

Procurement Notes

Verify the specific datasheet version provided by Fairview Microwave to confirm all electrical parameters match your system requirements. Ensure that the SMA interface orientation and heatsink mounting dimensions are compatible with your PCB layout. Confirm that the power supply voltage range of 12 V to 15 V aligns with your available power rails. Check for any regional distribution restrictions or lead time variations directly with authorized suppliers before finalizing procurement plans.

Selection Notes

Select this component when a wideband low noise amplifier is required for frequencies between 4 GHz and 12 GHz. The temperature compensation feature makes it suitable for environments with significant thermal fluctuations. Consider the 35 dB minimum gain and 4 dB noise figure for applications prioritizing signal integrity over maximum sensitivity. The integrated heatsink simplifies thermal design compared to bare die solutions.
