Maxim has introduced what it says is the industry's smallest linear power amplifier (PA) designed for 2,4 GHz WLAN applications. The MAX2242 PA is packaged in the ultra-small 3x4 chip-scale package (CSP) measuring 1,5 x 2,0 mm, making it ideal for portable WLAN radios built-in small PC card and compact flash card form factors. The small, yet high-performance PA delivers 28,5 dB gain and +22,5 dBm linear output power with ACPR of up to 33 dBc first side lobe and up to 56 dBc second side lobe, compliant with the IEEE-802.11b 11MBps WLAN standard with at least 3 dB margin.
The MAX2242 PA integrates a three-stage power amplifier, power detector, and power management circuitry. 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 maintaining sufficient ACPR performance. As a result, high efficiency is maintained at all power levels.
The device operates on a single +2,7 to +3,6 V supply. An on-chip shutdown feature reduces operating current to 0,5 µA. A fully assembled evaluation kit (MAX2242EVKIT) is available to help reduce design time.
