WJA1021 级联增益块
The TriQuint WJA1021 is a cascadable gain block that offers high linearity in a low-cost surface mount package. At 1.9 GHz, the WJA1021 typically provides 17.5 dB gain, +36.5 dBm OIP3 and +19 dBm P1dB. The device is housed in a lead-free / green / RoHS compliant industry-standard SOT-89 surface mount package using a NiPdAu plating to eliminate the possibility of tin whiskering. The WJA1021 consists of 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 1.9 GHz while drawing very low current. The MMIC amplifier is internally matched to 50 Ohm 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 +5 V 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 WJA1021 is ideal for general purpose applications such as LO buffering or amplification and pre-driver stages within the 50 to 4000 MHz frequency range.
