At 200 MHz, the WJA1510 typically provides 15 dB gain, +43 dBm OIP3, and +20 dBm P1dB. The device is housed in a lead-free/green/RoHS-compliant SOT-89 industry-standard SMT package using a NiPdAu plating to eliminate the possibility of tin whiskering. Operational Bandwidth Test Frequency Gain Input Return Loss Output Return Loss Output P1dB Output IP3 (2) Noise Figure Device Voltage Device Current GND 4 The WJA1510 consists of Darlington pair amplifiers using a high reliability InGaP/GaAs HBT process technology. The MMIC amplifier is internally matched to 50 and only requires DC-blocking capacitors and an inductive RF choke for operation. Biased directly from a 5V supply, an internal active bias network enables stable operation over temperature, eliminating the need for the typical dropping bias resistor. 1 2 3 RF IN GND RF OUT Function Input Output/Bias Ground Pin No. 1 3 2, 4 The amplifier is targeted for high performance IF applications in existing and next generation wireless technologies. In addition, the WJA1510 will work for various other applications within the 50 to 1000 MHz frequency range. .

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.
