www.DataSheet4U.com WJA1505 +5V Active-Bias InGaP HBT Gain Block Product Features 50 – 1000 MHz 19.5 dB Gain +19 dBm P1dB +35 dBm OIP3 +5V Single Voltage Supply Internal Active Bias Supply Internally matched to 50 Ω Lead-free / RoHS-compliant / Green SOT-89 package Product Description The WJA1505 is a high performance amplifier that offers high linearity in a low-cost surface-mount package. At 200 MHz, the WJA1505 typically provides 19.5 dB gain, +35 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 WJA1505 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 WJA1505 will work for various other applications within the 50 to 1000 MHz frequency range. RF IN Function Input Output/Bias...
