WJA1001 Product Features  50 – 3000 MHz  19 dB Gain @ 900MHz  +20 dBm P1dB @ 900MHz www.datasheet4u.com  +45 dBm OIP3 @ 900MHz  +5V Single Supply  Low current draw (100 mA)  Unconditionally stable  Internally matched to 50   Robust 1000V ESD, Class 1C  Lead-free/green/RoHS-compliant SOT-89 package +5V Active-Bias InGaP HBT Gain Block Product Description The WJA1001 is a cascadable gain block that offers high linearity in a low-cost surface-mount package. At 900 MHz, the WJA1001 typically provides 19 dB gain, +45 dBm OIP3, and +20 dBm P1dB. The device is housed in a leadfree/green/RoHS-compliant SOT-89 SMT package using a NiPdAu plating to eliminate the possibility of tin whiskering. The WJA1001 consists of a Darlington-pair amplifier using a high reliability InGaP/GaAs HBT process technology. The amplifier has been optimized internally to offer very high linearity performance at 1 GHz while drawing very low current. 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 and allow for operation 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 WJA1001 is ideal for general purpose applications such as LO buffering or amplification and pre-driver stages within the 50 to 3000 M...
