At 200 MHz, the WJA1515 typically provides 15 dB gain, +38 dBm OIP3, and +19 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. Functional Diagram GND 4 1 2 GND 3 RF OUT Applications • • • • • IF Amplifier Repeaters, BTS Transceivers VHF/UHF Wireless Infrastructure General Purpose The WJA1515 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. 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. The amplifier is targeted for high performance IF applications in existing and next generation wireless technologies. In addition, the WJA1515 will work for various other applications within the 50 to 1000 MHz frequency range.
