PRODUCT DESCRIPTION
The ANADIGICS AWL9224 power amplier is a high
performance InGaP HBT IC designed for transmit
applications in the 2.4-2.5 GHz band. Matched to
50 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
congurations 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 50 system.

PIN NAME DESCRIPTION
1GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
2RF
IN
RF Input. AC coupled input stage internally matched to 50 Ohms. Route as coplanar
waveguide using adjacent ground pins.
3GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
4GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
5 V
BC
Bias Circuit Voltage. Supply voltage and current is applied to this pin to apply power to
the bias circuits inside the PA.
6V
PC
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.
7DET
DC
Detector Bias. Supply voltage and current is applied to this pin to apply power to the
detector circuits inside the PA.
8DET
OUT
Power Detector Output. DC coupled. An emitter follower BJT supplies the output for
this pin.
9GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
10 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
11 RF
OUT
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.
12 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
13 V
CC3
Supply Voltage. Bias for power transistor of stage 3.
14 V
CC2
Supply Voltage. Bias for power transistor of stage 2.
15 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
16 V
CC1
Supply Voltage. Bias for power transistor of stage 1.
25 GND Ground slug on the underside of the LPCC package.

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not
implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely
affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is guaranteed
only over the conditions dened in the electrical specications.
Note:
(1) Applied to series resistors external to VPC pin.
