2.4GHz SiGe Linear Power Amplifier
General Description
The MAX2247 low-voltage, three-stage linear power
amplifier (PA) is optimized for 802.11b/g wireless LAN
(WLAN) applications in the 2.4GHz ISM band. The
device is integrated with an adjustable bias control,
power detector, and shutdown mode. The MAX2247
features 29dB of power gain and delivers up to
+24dBm of linear output power at 24% efficiency from a
single +3.3V supply. It achieves less than -32dBc first-
side lobe suppression and less than -55dBc second-
side lobe suppression under 802.11b modulation. In
addition, the device can be matched for optimum effi-
ciency and performance at output power levels from
+10dBm to +24dBm. Its high +28dBm saturated output
power also allows the device to meet the requirements
of 802.11g OFDM modulation.
The MAX2247 features an external bias-control pin that
allows the supply current of the device to be dynamical-
ly throttled back at lower output power levels, thus
improving efficiency while maintaining sufficient side-
lobe suppression. Proprietary internal bias circuitry

maintains stable device performance over temperature
and voltage-supply variations. An additional power-sav-
ing feature is a logic-level shutdown pin that reduces
supply current to 0.5μA and eliminates the need for an
external supply switch. The integrated shutdown func-

tion also allows guaranteed device ramp-on and ramp-
off times.
The MAX2247 integrates a power detector with 20dB
dynamic range and ±0.8dB accuracy at the highest
output power level. The detector provides a buffered
DC voltage proportional to the output power of the
device, saving cost and space by eliminating a coupler
and op amp usually required to implement a power
detector function. The device is packaged in the tiny
3 ? 4 chip-scale package (UCSP?), measuring only
