Additional Details

The PE4248 operates over a broad frequency range, typically from 100 MHz to 6 GHz, making it versatile for a wide range of RF applications. It is fabricated using Peregrine's UltraCMOS® process technology, ensuring high performance and reliability. The switch is available in a compact QFN package, making it suitable for space-constrained designs. The high power handling capability makes it ideal for applications where the RF signal strength is substantial. The high IIP3 ensures that the switch introduces very little distortion, which is critical in applications where signal fidelity is paramount. The low insertion loss helps to maintain signal strength, while the high isolation prevents unwanted signals from leaking through.
