Qorvo's WJA1505 is a cascadable gain block that offers high linearity in a low-cost surface mount package. At 200 MHz, the WJA1505 typically provides 19 dB gain, +37 dBm OIP3 and +19 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 WJA1505 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 +5 V supply voltage.
The amplifier is targeted for high performance IF applications in existing and next generation wireless technologies. The WJA1505 is ideal for general purpose applications such as LO buffering, IF amplification and pre-driver stages within the 50 to 1000 MHz frequency range.
