RF Amplifier Modules

OEM Amplifier and Low-Noise Modules for Custom RF Chain Integration

Not every RF amplification requirement calls for a complete, standalone rack-mount instrument ready to drive a test antenna directly — an engineer building a custom RF chain, a radar front-end, or an EMC test fixture often needs a matched gain block at a specific frequency and power point, integrated into a larger system rather than sitting on a bench as its own instrument. RFlight's RF Amplifier Modules range is built for exactly this: compact, board- or chassis-level amplifier and low-noise modules for custom RF chain integration.

This distinguishes the range clearly from RFlight's standalone CW and pulsed power amplifiers in the main RF & EMC Power Amplifiers line — those are complete rack-mount instruments ready to drive a test antenna directly out of the box, while these modules are the building blocks an integrator assembles inside a larger system, whether that's a satellite payload, a custom test fixture, or an OEM sub-assembly being designed from the ground up.

For engineers designing a custom system rather than buying a ready-to-use test instrument, these modules provide the amplification building block without the enclosure, front panel, and control interface that a standalone instrument carries — and without the added cost of features the custom integration doesn't need.

Frequently Asked Questions

How do RF Amplifier Modules differ from RFlight's standalone RF & EMC Power Amplifiers?

The standalone amplifiers are complete rack-mount instruments ready to connect directly to a test antenna or fixture. These modules are board- or chassis-level building blocks intended to be integrated into a larger custom system by an engineer or integrator, rather than used as a standalone bench instrument.

What kind of projects typically use OEM amplifier modules like these?

Custom RF chain builds, radar front-end development, EMC test fixture design, satellite payload integration, and other OEM sub-assemblies where a matched gain block at a specific frequency and power point is needed as one component within a larger system being designed.

Should I choose a module or a standalone amplifier for my application?

Where the requirement is a ready-to-use instrument that connects directly to a test antenna or fixture, a standalone amplifier from RFlight's main power amplifier line is the appropriate choice. Where the requirement is a component to integrate into a custom-built system, these OEM modules are the more suitable and typically more cost-effective option.

Where This Fits

These modules aren't complete test instruments — they're gain blocks and LNAs meant to be integrated into a larger assembly, whether that's a custom-built test fixture, a satellite payload, or an OEM sub-system. If you need a ready-to-use bench or rack amplifier instead, see the standalone RF & EMC Power Amplifiers series.
