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.
