Product Details

Characteristics and Applications

The Miniaturized Microstrip Circulator series finds applications in various fields where space constraints and specific assembly size requirements are crucial. These compact circulators are well-suited for integration into miniaturized communication systems, phased array antennas, portable radar systems, and compact RF/microwave modules. Additionally, they are utilized in emerging technologies such as wearable devices, IoT (Internet of Things) sensors, and miniaturized satellite communication systems, where their small form factor and high performance are essential for seamless integration and efficient operation.

Key Features & Advantages

1. Ultra-Compact Size & Lightweight:
   • Volume and weight can be reduced by 50% to 80% compared to traditional waveguide or stripline circulators, with typical sizes as small as a few millimeters square.
   • Ideal for highly integrated modules (e.g., T/R modules, within RFIC packages).
2. High Isolation & Low Insertion Loss:
   • High Isolation: Typically better than 20 dB, effectively preventing transmitted signal leakage into the receive channel and protecting sensitive receivers.
   • Low Insertion Loss: Typically less than 0.5 dB, ensuring high signal transmission efficiency and low system noise figure.
3. Wide Operating Bandwidth:
   • Can be designed for various relative bandwidths per customer requirements, from narrowband (3-5%) to broadband (up to an octave), satisfying different system needs.
4. High Power Handling Capacity:
   • Despite their small size, through optimized thermal design and material selection, they can handle average power from several watts to tens of watts, with some products handling peak power up to the kilowatt level.
5. Excellent Temperature Stability & Reliability:
   • Utilizes temperature-compensated magnetic circuits or wide-temperature ferrites to ensure stable performance across an operating temperature range of -40°C to +85°C (or wider).
   • Robust mechanical structure with strong resistance to vibration and shock, suitable for military and harsh environment applications.
6. Surface-Mount Technology (SMT) Compatibility:
   • Most miniaturized microstrip circulators are designed for surface mounting, compatible with automated pick-and-place production, significantly improving assembly efficiency, consistency, and reducing production costs.

Typical Applications

Miniaturized microstrip circulators act as "traffic police" in modern wireless systems and are widely used in:

• Radar Systems: Especially in T/R modules for phased array radars, used to share and isolate transmit and receive channels.
• 5G/6G Communication Infrastructure: RF units in Massive MIMO base stations for transmit/receive duplexing.
• Satellite Communication & Navigation: Airborne, shipborne, vehicle-mounted mobile terminals with stringent size and weight requirements.
• Test & Measurement Instruments: Spectrum analyzers, vector network analyzers, etc., as core switching or isolation components.
• IoT Devices & Terminals: Drones, wearable devices, and other scenarios requiring compact RF front-ends.
• Military & Aerospace Electronics: Missile seekers, electronic warfare equipment, etc.
