RF Amplifier Modules

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

These are compact, board- or chassis-level amplifier and low-noise modules — not standalone bench instruments. They're intended for engineers building a custom RF chain, radar front-end, or EMC test fixture who need a matched gain block at a specific frequency and power point, rather than a complete turnkey test amplifier.

This distinguishes them from the standalone CW and pulsed power amplifiers in RFlight's main RF & EMC Power Amplifiers line: those are rack-mount instruments ready to drive a test antenna directly, while these modules are the building blocks an integrator uses inside a larger system — a satellite payload, a custom test fixture, or an OEM sub-assembly.

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.
