Frequently asked questions
The stuff you actually want to know.
Touchstone files: .s2p and .s1p (1-port and 2-port S-parameters). Designs are saved and exported as JSON.
Cascade analysis calculates the cumulative gain, noise figure, and P1dB compression point across a chain of RF components — amplifiers, filters, mixers, etc. It's how you know if your signal chain actually works before you build it.
Not yet on the standard plans. If you need on-premise deployment, reach out about our Enterprise tier.
Yes. Upgrade or downgrade anytime. Prorated billing, no penalties.
A link budget accounts for all gains and losses in a communication link — transmit power, antenna gains, path loss, cable losses — to determine if you have enough signal margin at the receiver.
Yes, within 30 days. No questions asked.
