Product Description

The AH201 is a 1-Watt driver amplifier that offers
excellent dynamic range in a low-cost, 6 x 6 mm 10-pin
QFN surface-mount package. Biased at +11 V, this
device provided its optimum P1dB and OIP3
performance; it can be biased as low as +9 V for lower
power applications.

The backside metalization provides excellent thermal
dissipation while allowing visible evidence of solder
reflow across the bottom of the package on a SMT board.
Superior thermal design allows the product an MTBF of
over 100 years at a mounting temperature of +85 C. All
devices are 100% RF & DC tested.

The product is targeted for use as a driver amplifier for
wireless infrastructure or CATV applications where high
linearity and medium power is required.

Test conditions unless otherwise noted.
1. T = 25C, Vdd = 11 V, Frequency = 900 MHz in an application circuit.
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 10 MHz.
The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. IS-95, 9 Channels Forward, Pk/Avg Ratio = 11.5 dB at a .001% probability
750 kHz offset, 30 kHz bandwidth, Channel BW = 1.23 MHz, frequency = 860 MHz
4. The maximum junction temperature ensures a minimum MTTF rating of 1 million hours of
usage. The MTTF plot and more information is located on the WJ App Note
"Temperature Effects on Reliability for the AH201" located on the WJ website.

Typical Device Data
S-parameters (Vd = +11 V, Id = 350 mA, unmatched device in a 50
system).
Measurements are shown for an unmatched packaged device with the data being de-embedded to the device leads.
The amplifier requires a matching network at the input for proper operation. The amplifier is intrinsically well matched at the output
and ideally should "look" into 50
. Any deviation from this can affect the linearity IP3 performance for the device.

Product Information
The Communications Edge
TM
Application Circuit PC Board Layout and Schematic
for 900 MHz, 1900 MHz, and 2140 MHz Reference Designs
Pin 4 is used as a location for internal matching
with bond wires. This pin should not be
grounded for proper operation.
Gap is .010". Pad is .044" x .057".
Trace at the edge of the pad is .038 wide and tapers
to .023 wide to match width of pin 4.
Notes:
Via holes are omitted for clarity.
The microstrip line is weakly co-planer. Ground planes around it are
not necessary for operation of the AH201.
Adequate heat sinking is required for the device. Further mounting
instructions are shown in the "Mounting Configuration".
The RF choke should be a wirewound ceramic type to insure sufficient
current carrying capacity. TOKO's LLQ1608 series is recommended.
Pin 4 should contain a stub as shown above.

Mounting Configuration Notes:

1. Ground vias are critical for thermal and RF grounding considerations.
2. Two 2-56 screws with washers should be used for thermal grounding to the main chassis.
3. Ground plane on the backside should extend past the holes for the 2-56 screws as a
minimum.
4. No soldermask should be applied to the backside of the board local to the part to ensure
contact between the backside metalization and chassis.
5. Via holes and holes for the 2-56 screws should be plated through.
6. Trace width depends on the PC board.
7. A minimum of 1 oz. / 1 oz. Copper should be used.
8. Pin 4 should not be connected for proper operation.

Please refer to the application note located on the website for further information:
