The WJA high-performance broadband amplifiers provide a mix of power gain, linearity and supply current performance in a SOT-89 package, enabling designers to integrate with their designs. The devices are internally matched to 50 ohm and only require DC-blocking/bypass capacitors and a bias inductor for operation. The amplifiers utilise the InGaP/GaAs HBT process technology and are suitable for current and next-generation wireless applications such as GSM, PCS, CDMA, W-CDMA, WiBro and WiMax, Repeaters, BTS Transceivers and RFID.
WJA1001 provides 19dB gain at 900MHz, a +20dBm 1-dB compression point,and +45dBm OIP3 at 900MHz, while drawing 100mA of current from a 5V supply voltage. The WJA1021 gain block amplifier offers +37.5dBm OIP3 at 1.9GHz and is suitable for high-linearity applications in the 50 to 4000MHz frequency range. At 1.9GHz, the device typically provides 17.5dB gain, +37.5dBm OIP3, and19dBm P1dB, drawing 90mA current from a 5V supply.
"Having the newest products on the shelf at Mouser allows our engineering customers to design with the latest technologies," said Mike Scott, vice president, active products, Mouser. "RF system designers consistently need products with improved linearity and other electrical and physical characteristics like these gain blocks from TriQuint-WJ." |
