Product Features
Product Description
Functional Diagram
GND
The WJA1000 is a high performance amplifier that offers
high linearity in a low-cost surface-mount package. At 900
MHz, the WJA1000 typically provides 19 dB gain, +37
dBm OIP3, and +19.5 dBm P1dB. The device is housed in
• 50 – 4000 MHz
• 19 dB Gain
• +19.5 dBm P1dB
• +37 dBm OIP3
• +5V Single Voltage Supply
• Internal Active Bias Supply
• Internally matched to 50 Ω
• Lead-free / RoHS-compliant /
Green SOT-89 package

a
lead-free/green/RoHS-compliant SOT-89 industry-
standard SMT package using a NiPdAu plating to eliminate
the possibility of tin whiskering.

The WJA1000 consists of Darlington pair amplifiers using
a high reliability InGaP/GaAs HBT process technology.
The MMIC amplifier is internally matched to 50Ω and only
requires DC-blocking capacitors and an inductive RF choke
for operation. An internal active bias is designed to enable
stable performance over temperature. It also eliminates the
need for a dropping bias resistor and allows the device to
be biased directly from a +5V supply voltage.

Mounting Config. Notes
1. Ground
/ thermal vias are critical for the proper
performance of this device. Vias should use a .35mm
(#80 / .0135”) diameter drill and have a final plated thru
diameter of .25 mm (.010”).
2. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
3. Mounting screws can be added near the part to fasten the
board to a heatsink. Ensure that the ground / thermal via
region contacts the heatsink.
4. Do not put solder mask on the backside of the PC board in
the region where the board contacts the heatsink.
5. RF trace width depends upon the PC board material and
construction.
6. Use 1 oz. Copper minimum.
7. All dimensions are in millimeters (inches). Angles are in
degrees.
