SiGeHBT amplifier QPA4486A original spot
QPA4486A: DC – 4500 MHz Cascaded SiGe HBT Amplifier. Company advantage inventory.
General Instructions
The QPA4486A is a high performance SiGe HBT MMIC
amplifier. Darlington configuration provides high FT and
Excellent thermal properties. Heterojunction
Increases breakdown voltage and minimizes leakage
current between connection points. Cancel the emitter junction
Nonlinearity leads to higher rejection
intermodulation products. There are only two DC blocking capacitors,
Requires a bias resistor and an optional RF choke for operation
