RMPA2458 Rev. E
Electrical Characteristics1 802.11b CCK Modulation
(RF not framed) 11 Mbps Data Rate 22.0 MHz Bandwidth
Electrical Characteristics1 Single Tone
Notes:
1. VC1, VC2, VC3 = 3.3V, VM123 = 2.9 Volts, Ta = 25°C, PA is constantly biased, 50Ω system.
2. PIN is adjusted to point where performance approaches spectral mask requirements.
3. POUT measured at PIN corresponding to power detection threshold.
4. Mirror bias current is included in the total quiescent current.
5. Measured from Device On signal turn on to the point where RF POUT stabilizes to 0.5dB.
6. Load VSWR is set to 8:1 and the angle is varied 360 degrees. POUT = -30dBm to P1dB.
