General Description
The MAX2242 low-voltage linear power amplifier (PA) is
designed for 2.4GHz ISM-band wireless LAN applica-
tions. It delivers +22.5dBm of linear output power with
an adjacent-channel power ratio (ACPR) of <-33dBc
1st-side lobe and <-55dBc 2nd-side lobe, compliant
with the IEEE 802.11b 11MB/s WLAN standard with at
least 3dB margin. The PA is packaged in the tiny 3x4
chip-scale package (UCSP), measuring only 1.5mm x
2.0mm, ideal for radios built in small PC card and com-
pact flash card form factors.
The MAX2242 PA consists of a three-stage PA, power
detector, and power management circuitry. The power
detector provides over 20dB of dynamic range with
±0.8dB accuracy at the highest output power level. An
accurate automatic level control (ALC) function can be
easily implemented using this detector circuit.
The PA also features an external bias control pin.
Through the use of an external DAC, the current can be
throttled back at lower output power levels while main-
taining sufficient ACPR performance. As a result, the
highest possible efficiency is maintained at all power
levels. The device operates over a single +2.7V to
+3.6V power-supply range. An on-chip shutdown fea-
ture reduces operating current to 0.5μA, eliminating the
need for an external supply switch.
