Notes: (1) Harmonic levels and ACPR are greatly affected by topology of external matching networks.

(2) Parameter measured with RF modulation based on IEEE 802.11b standard and matching networks

optimized for linear output power performance

(3) With matching networks optimized for saturated output power performance

(4) Measured at VDET pin
