Calculation method
Calculation method
Input-referred individual stage limits (dBm)
Each supplied input compression point minus preceding gains.
Most restrictive input limit (dBm)
Minimum input-referred stage limit; conservative stage-wise screening only, not exact cascade P1dB.

Assumptions & limits
Assumptions & limits
- Stage gains, supplied compression points. Returns Approximate cascade constraint. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Stage gains (dB): minimum None, maximum 1000000000000.0. Stage input 1dB compression points (dBm): minimum None, maximum 1000000000000.0.
