S Band 2.9–3.3GHz Drop-in Isolator

Compact 100W Drop-in Isolator for S Band RF Front-End Protection

HzBeat's 2.9–3.3GHz Drop-in Isolator is designed for S band RF systems requiring low insertion loss, stable isolation, and compact mechanical integration.
With 100W CW power handling and a 13 × 13 × 8 mm package, it is suitable for RF front-end modules, transmit chains, and compact microwave assemblies.
The device provides 0.35 dB max insertion loss, 20 dB min isolation, 1.25 max VSWR, and clockwise direction for reliable S band signal protection.

Key Features & Advantages

S Band 2.9–3.3GHz Coverage: Optimized for S band RF modules, radar subsystems, microwave communication links, and transmitter protection circuits.
100W CW Power Handling: Suitable for RF paths requiring stronger power capability than typical microstrip-level isolator solutions.
Low Insertion Loss: 0.35 dB max insertion loss helps reduce power loss and improve overall RF chain efficiency.
20 dB Isolation: 20 dB min isolation helps suppress reflected power and protect upstream RF components.
Compact Drop-in Package: The 13 × 13 × 8 mm outline supports compact module integration while maintaining practical power handling.
Wide Temperature Operation: Designed for –55°C to +85°C operating environments in demanding RF and microwave applications.

Typical Applications

S band RF front-end modules
Radar transmitter and receiver protection circuits
Power amplifier output protection
Microwave communication equipment
Phased-array and active antenna systems
Test and measurement equipment
Compact RF systems requiring 100W CW power handling
