Product Description
The WJA1030 is a cascadable gain block that offers high linearity in a low-cost surface-mount package. At 1.9 GHz, the WJA1030 typically provides 15 dB gain, +37 dBm OIP3, and +18 dBm P1dB. The device is housed in a RoHS-compliant SOT-89 industry-standard SMT package
using a NiPdAu plating to eliminate the possibility of tin whiskering.
The WJA1030 consists of Darlington pair amplifiers using a high reliability InGaP/GaAs HBT process technology. The MMIC amplifier is internally matched to 50 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 +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 WJA1030 is ideal for general purpose applications such as LO buffering, IF amplification and pre-driver stages within the 50 to 4000 MHz frequency range.
