Additional Details

The PE4261 operates over a wide frequency range, typically from 100 MHz to 6 GHz, making it suitable for diverse RF applications. The use of Peregrine's UltraCMOS® process technology ensures high performance and reliability. The SPDT switch is available in a small QFN package, making it ideal for space-constrained designs. Its high IIP3 ensures that the switch introduces very little distortion, critical for applications where signal fidelity is paramount. The low insertion loss helps maintain signal strength, and the high isolation prevents unwanted signals from leaking through. It also supports CMOS logic control for ease of integration.
