WJA1020 级联增益块
The TriQuint 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 surface mount package using a NiPdAu plating to eliminate the possibility of tin whiskering. The WJA1020 consists of Darlington pair amplifiers using a high reliability InGaP / GaAs HBT process technology. 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. A dropping bias resistor is not required allowing the device to be biased 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 WJA1020 is ideal for general purpose applications such as LO buffering, IF amplification and pre-driver stages within the 50 to 4000 MHz frequency range.
