I.Product Overview

This featured product is a high-power 3-port ferrite drop-in circulator operating within the 1200–1400?MHz frequency range, precisely covering the core operating band of the L?band. Adopting an integrated embedded mounting structure, it is specially designed for PCB onboard integration, high?power amplifier chains, low?altitude detection radar, satellite ground receiving equipment, and high?power IoT RF transmission systems.

Leveraging the non?reciprocal transmission property of gyromagnetic ferrite materials, it enables unidirectional circulating transmission of electromagnetic waves. It effectively isolates reflected power caused by antenna impedance mismatch and crosstalk between transmit and receive channels, fundamentally safeguarding the stable operation of key active components such as power amplifiers. It serves as an essential passive component for high?power RF systems operating in the L?band.
