Broadband Drop-in Circulator

2-6GHz, 6-18GHz, Full Band.

The Broadband Drop-In Circulator represents the evolution of circulator technology towards high performance, high density, and high reliability. Its innovative "drop-in" design perfectly meets the stringent demands for miniaturization, weight reduction, and high power in modern radar, 5G, and defense electronic systems, making it the preferred component for advanced RF engineers building compact, high-performance systems.

Product Details

Characteristics and Applications

The Broadband Drop-in Circulator is an essential component in RF systems, specifically designed to provide high isolation and efficient signal routing in a compact and convenient drop-in package. This circulator is engineered to effectively route RF signals in a unidirectional manner, allowing for seamless signal flow while minimizing signal loss and reflections.

Its robust construction and high-quality materials enable it to maintain superior isolation and signal routing capabilities, making it an ideal choice for demanding RF environments. The drop-in design allows for easy integration into existing RF systems, providing a convenient solution for enhancing overall system performance.

Key Features & Advantages

• Wide Bandwidth Operation: Its most prominent feature. A single device can cover a very wide frequency range (e.g., 0.5-2 GHz, 2-8 GHz), reducing the number of components needed in a system and simplifying design.
• High Isolation: Within the specified frequency band, the reverse isolation is very high (typically >20 dB, with high-quality products reaching >25 dB). This means the signal leaking from Port 2 back to Port 1 is very weak, effectively preventing damage to preceding circuits (like power amplifiers) from reflected signals.
• Low Insertion Loss: The signal attenuation in the forward path is very small (typically <0.5 dB, with high-quality products reaching <0.3 dB), ensuring signal transmission efficiency.
• High Power Handling Capacity: Capable of withstanding high average and peak power levels, making it suitable for transmit paths in radar and communication systems.
• Compact Structure, Easy Integration: The stripline structure is inherently small, lightweight, and very suitable for modern compact microwave modules and PCB-level integration.
• High Reliability and Stability: Typically housed in a fully sealed metal package, offering good mechanical strength, heat dissipation, and environmental resilience (e.g., temperature, humidity, vibration).

Typical Applications

• Radar Systems:Connects the transmitter, antenna, and receiver. During transmission, it directs high-power signals to the antenna; during reception, it directs weak echo signals to the receiver, protecting the transmitter from damage by reflected power.
• Communication Base Stations (especially TDD Systems):In Time Division Duplexing systems, a circulator allows a single antenna to be used for both transmission and reception, simplifying antenna design and the RF front-end architecture.
• Test & Measurement Equipment:
• Used in signal generators, spectrum analyzers, and network analyzers for signal routing and isolation.
• Electronic Warfare (EW):Used for signal switching, routing, and isolation across wide frequency bands.
• Multiband/Broadband Amplifiers:Serves as an output isolator, stabilizing amplifier operation, improving its output match, and absorbing reflected power from the antenna side.
