When Every Picosecond Counts: Inside the SD5400 Quad Switch

In radar systems, even nanoseconds can be too slow. Our SD5400 quad switch is engineered for peak performance when every picosecond counts. It delivers sub-nanosecond switching in a compact form—ideal for precision applications like high-speed radar tracking.

Key Advantages

• Ultra-fast switching: t_ON/t_OFF ≤ 1 ns — ideal for high-frequency digital and analog routing.

• Low capacitance, low loss: Input QrSS ~0.5 pF, enabling clean signal paths with minimal distortion.

• Robust analog handling: Supports ±10 V analog signals with low RDS(on) (~75 Ω @ VGS = 5 V).

• Defense-grade reliability: Bidirectional, zener‑protected gates and comprehensive ESD protection ensure ruggedness for harsh environments.

Why It Matters

Radar and many other systems rely on split-second precision:

• Sub-ns switching removes signal latency, improving tracking accuracy and system responsiveness.

• X‑axis signal integrity—with low capacitance, these switches reduce insertion loss and maintain clean waveforms across chained paths.

• Compact, rugged packaging supports tight board constraints and meets military and aerospace standards.
