QPA5389A

QPA5389A ® DC – 4500 MHz Cascadable SiGe HBT Amplifier General Description The QPA5389A is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration provides high FT and excellent thermal performance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. Only two DC-blocking capacitors, a bias resistor, and an optional RF choke are required for operation. 3 Lead SOT-89 Package Functional Block Diagram Product Features  High Gain: 15.9 dB at 1950 MHz  Cascadable 50 Ω  Operates from Single Supply  Low Thermal Resistance Package Applications  Instrumentation  Repeaters  Boosters  PA Driver Amplifier  Cellular, PCS, GSM, UMTS  IF Amplifier  Wireless Data, Satellite Top View Data Sheet Rev.B, August 12, 2016 | Subject to change without notice Ordering Information Part No. QPA...
