GChain

Model your whole signal chain before you build it.

GChain is Guerrilla RF's free online RF link budget tool. Drop amplifiers, mixers, filters and attenuators into a lineup and watch the cascaded performance update as you go — no spreadsheet, no install.

What It Does

Back-of-envelope math, without the envelope.

Cascade the key numbers

Build a receive or transmit lineup stage by stage and see cascaded gain, noise figure, linearity and compression roll up across the whole chain.

Real Guerrilla RF devices

Pull our amplifiers, gain blocks, mixers, switches and attenuators straight into the lineup so the model reflects parts you can actually buy.

Try the what-ifs

Swap a stage, reorder the chain or change the drive level and compare the result — the fast sanity check before anything hits a schematic.

Runs in the browser

Nothing to install and no licence to chase. GChain runs anywhere you have a browser, so it's there when the question comes up mid-meeting.

Save your work

Save a chain to your account and pick it back up later — so the lineup you worked out this month is still there when the design comes back around.

Our engineers behind it

GChain was built in-house by the same applications team that supports our parts. Tell us what it's missing — we read every note.
