The QPA0363A from Qorvo is a Darlington Pair SiGe HBT MMIC Gain Block amplifier that operates from DC to 5 GHz. It provides an output power of 21.7 dBm at 1950 MHz and a gain of 12.9 dB with a noise figure of 3.8 dB. This device may be operated from a variety of supply voltages by using a voltage dropping resistor. Two DC-blocking capacitors, bypass capacitors and an optional RF choke complete the circuit required for operation of this internally matched 50 ohm device. It is available in a lead-free, RoHS-compliant SOT- 363 package and is ideal for wireless data, satellite, cellular and buffer amplifier applications.
