FMWGA3218

Overview

The FMWGA3218 is a WR-19 waveguide power amplifier manufactured by Fairview Microwave, designed for the U Band frequency range of 40 GHz to 60 GHz. It features a nominal gain of 40 dB and delivers a saturated output power (Psat) of 24 dBm. The device utilizes a UG-383/U-M flange interface for waveguide connection. Electrical operation requires a supply voltage between 5 V and 10 V, with an operating current consumption of 450 mA. This component serves as a high-frequency signal amplification solution within its specified band.

Feature Summary

• Operates in the U Band covering 40 GHz to 60 GHz frequencies
• Provides 40 dB nominal gain with 24 dBm saturated output power
• Utilizes WR-19 waveguide structure with UG-383/U-M flange

Applications

• U Band radar systems
• Satellite communication uplinks
• Point-to-point microwave links
• Electronic warfare applications

Procurement Notes

Verify the specific flange configuration and mating hardware requirements before procurement. Confirm that the power supply meets the 5 V to 10 V voltage range and can provide at least 450 mA continuously. Ensure thermal management solutions are adequate for the power dissipation characteristics of this amplifier module. Cross-reference the datasheet for precise mechanical dimensions and mounting torque specifications.

Selection Notes

Select the FMWGA3218 when a fixed-gain, high-power amplification stage is required specifically for the 40 GHz to 60 GHz U Band spectrum. Compare performance metrics such as Psat and gain flatness against system link budget requirements. Consider the WR-19 waveguide interface compatibility with existing test fixtures or integrated systems. Evaluate thermal constraints and cooling methods necessary for sustained operation at 450 mA current draw.

Part Context

This model belongs to Fairview Microwave's line of waveguide power amplifiers, targeting millimeter-wave applications. It complements other models like the FMWGA3217, which operates in the lower Q Band (33 GHz to 50 GHz). Both utilize similar UG-383/U-M flanges but differ in frequency coverage and gain specifications, allowing for scalable system design across adjacent bands.
