At 900 MHz, the WJA1001 typically provides 19 d B gain, +45 d Bm OIP3, and +20 d Bm P1d B. The device is housed in a leadfree/green/Ro HS-pliant SOT-89 SMT package using a Ni Pd Au plating to eliminate the possibility of tin whiskering. The WJA1001 consists of a Darlington-pair amplifier using a high reliability In Ga P/Ga As 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, Wi Bro, and Wi MAX. The WJA1001 is ideal for general purpose applications such as LO buffering or amplification and pre-driver stages within the 50 to 3000 MHz frequency range.
