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.

VPC
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 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
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
configurations within these standards.

NAME
DESCRIPTION
1
GND
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
2
RFIN
RF Input. AC coupled input stage internally matched to 50 Ohms. Route as coplanar
waveguide using adjacent ground pins.
3
GND
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
4
GND
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.
5
VBC
Bias Circuit Voltage. Supply voltage and current is applied to this pin to apply power to
the bias circuits inside the PA.
6
VPC
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.
7
DETDC
Detector Bias. Supply voltage and current is applied to this pin to apply power to the
detector circuits inside the PA.
8
DETOUT
Power Detector Output. DC coupled. An emitter follower BJT supplies the output for
this pin.
9
GND
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
RFOUT
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
VCC3
Supply Voltage. Bias for power transistor of stage 3.
14
VCC2
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
VCC1
Supply Voltage. Bias for power transistor of stage 1.
25
GND
Ground slug on the underside of the LPCC package.

**NOTES**
1. RF traces should be 18 mils wide with 20 mils of clearance
2. DC traces should be 8 mils wide with 8 mils of clearance
3. Trace widths and clearances apply to application
circuit on 10 mil FR4
4. DNP = Do Not Place
5. Pin 25 is the metallized Ground slug on the LPCC package.
6. Pins 1, 3, 10, and 12 should be tied directly to PCB ground pattern
under Pin 25, and should form a coplanar waveguide for the RF In and
RF Out.
