RF switches are essential components in modern wireless systems, enabling antenna switching, band selection, and signal routing. Proper switch selection is critical for system performance.

Switch Types

SPDT: Single Pole Double Throw - most common for antenna switching.

DP4T: Double Pole Four Throw - enables multiple antenna switching.

Key Parameters

Isolation: Higher isolation reduces interference between paths. 20+ dB typical.

Insertion Loss: Lower is better - typically 0.3-0.5 dB for modern switches.

Switching Speed: Critical for time-division systems. 10-100 μs typical.
