WJA1020

WJA1020 Product Features +5V Active-Bias InGaP HBT Gain Block Product Description The WJA1020 is a cascadable gain block that offers high linearity in a low-cost surface-mount package. At 1.9 GHz, the WJA1020 typically provides 17 dB gain, +34 dBm OIP3, and +17 dBm P1dB. The device is housed in a RoHS-compliant SOT-89 industry-standard SMT package using a NiPdAu plating to eliminate the possibility of tin whiskering. Functional Diagram GND 4 Cascadable gain block 50 – 4000 MHz 17 dB Gain @ 1.9GHz +17 dBm P1dB @ 1.9GHz +34 dBm OIP3 @ 1.9GHz Operates from +5V @70mA Robust 1000V ESD, Class 1C RoHS-compliant SOT-89 package 1 2 GND 3 RF OUT Applications Wireless Infrastructure General Purpose Cellular GSM, PCS, UMTS W-CDMA, TD-SCDMA, WiMAX The WJA1020 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 a bias inductor for operation. An internal active bias is designed to enable stable performance over temperature. A dropping bias resistor is not required allowing the device to be biased directly from a +5V supply voltage. The broadband amplifier can be directly applied to various current and next generation wireless technologies such as GSM, CDMA, W-CDMA, WiBro, and WiMAX. The WJA1020 is ideal for general purpose applications such as LO buffering, IF amplification and pre-driver stages within the 50 to 4000 MHz...
