PRODUCT DESCRIPTION
The ANADIGICS AWL9224 power amplifier is a high performance InGaP HBT IC designed for transmit applications in the 2.4-2.5 GHz band. Matched to 50V at the input and output, the part requires no additional RF matching components off-chip. The PA exhibits unparalleled linearity for both IEEE 802.11g and 802.11b WLAN systems under the toughest signal configurations within these standards. The power detector is temperature compensated on the chip, enabling a single-ended output voltage with excellent accuracy over a wide range of operating temperatures. The PA is biased by a single +3.3 V supply and consumes ultra-low current in the OFF mode. The AWL9224 is manufactured using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and ruggedness. The AWL9224 is RoHS (Restrictions on Hazardous Substances) compliant. It is provided in a 3 x 3 x 0.9 mm LPCC package optimized for a 50V system.

AWL9224 Table 1: Pin Description PIN 1 2 3 4 5 NAME GND RFIN GND GND V BC DESCRIPTION Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. RF Input. AC coupled input stage internally matched to 50 Ohms. Route as coplanar waveguide using adjacent ground pins. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. Bias Circuit Voltage. Supply voltage and current is applied to this pin to apply power to the bias circuits inside the PA. Power amplifier power control pin. The recommended use is for on/off control of the PA. Nominally, 0 V applied will turn amplifier completely off; +3.3 V should be used to set amplifier to maximum output capability. A series resistor is used to set the current flow into the pin, thereby controlling the overall bias level of the PA. Detector Bias. Supply voltage and current is applied to this pin to apply power to the detector circuits inside the PA. Power Detector Output. DC coupled. An emitter follower BJT supplies the output for this pin. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. RF Output. AC coupled output stage internally matched to 50 Ohms. Route as coplanar waveguide using adjacent ground pins. A shunt inductive matching element included inside the PA after the AC coupling capacitor provides a DC path to ground at this pin. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. Supply Voltage. Bias for power transistor of stage 3. Supply Voltage. Bias for power transistor of stage 2. Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. Supply Voltage. Bias for power transistor of stage 1. Ground slug on the underside of the LPCC package.
