QPA5389A DC4500MHz Cascadable SiGe HBT Amplifier General Description The QPA5389A is a high performance SiGe HBT MMIC Amplifier. The QPA5389A uses a Darlington configuration which provides flat gain and good linearity over a wide frequency range. The QPA5389A has excellent thermal performance. The QPA5389A is internally matched to 50 at input and output requiring only two DC-blocking capacitors, a resistor, 3 Lead SOT-89 Package and an optional RF choke for operation. The QPA5389A operates from a single supply and has stable bias current. The QPA5389A is cascadable with other amplifiers.
