PA Linearity & P1dB Design Helper

Enter RF output requirements and the tool recommends PA P1dB, OIP3 and linearity margins.

PA Requirements

Required output power (dBm) Peak-to-average ratio (PAPR) of modulation (dB) Required linearity margin (dB) Required ACLR / EVM headroom (dB)

Results will appear here.

Key Equations

P1dB_required = P_out + PAPR + linearity_margin + ACLR_margin

OIP3_required ≈ P1dB_required + 9.6 dB

Modern modulations require PA to operate well below saturation to maintain EVM/ACLR.
