WJA1021 +5V Active-Bias InGaP HBT Gain Block Product Features Product Description Functional Diagram GND The WJA1021 is a cascadable gain block that offers high 50 4000 MHz linearity in a low-cost surface-mount package. At 1.9 GHz, 4 17.5 dB Gain 1.9GHz the WJA1021 typically provides 17.5 dB gain, +36.5 dBm +19 dBm P1dB 1.9GHz OIP3, and +19 dBm P1dB. The device is housed in a lead- free/green/RoHS-compliant industry-standard SOT-89 +36.5 dBm OIP3 1.9GHz SMT package using a NiPdAu plating to eliminate the +5V Single Supply possibility of tin whiskering. 1 Low current draw (90mA) 2 3 The WJA1021 consists of Darlington pair amplifier using a RF IN GND RF OUT Unconditionally stable high reliability InGaP/GaAs HBT process technology. Internally matched to 50 The amplifier has been optimized internally to offer very Function Pin No. high linearity performance at 1.9 GHz while drawing very Robust 1000V ESD, Class 1C Input 1 low current. The MMIC amplifier is internally matched to Output/Bias 3 Lead-free/green/RoHS-compliant 50 and only requires DC-blocking capacitors and a bias Ground 2, 4 SOT-89 package inductor for operation. An internal active bias is designed to enable stable performance over temperature and allow for operation directly from a +5V supply voltage. Applications The broadband amplifier can be directly applied to various GSM, PCS, CDMA, WCDMA current and next generation wireless technologies such as GSM, CDMA, W-CDMA, WiBro, and WiMAX. The WiMAX, WiBro WJA1021 is ideal for general purpose applications such as Repeaters, BTS Transceivers LO buffering or amplification and pre-driver stages within RFID the 50 to 4000 MHz frequency range.
