Product Details
Characteristics and Applications
The Broadband Microstrip Circulator series is characterized by its wider frequency bandwidth, covering two
main frequency ranges: 2-6GHz and 6-18GHz. These circulators find extensive applications in fields such as
communication, radar, and radio frequency spectrum analysis. Their wide bandwidth makes them an ideal choice
for high-frequency signal transmission and isolation, and they are also suitable for use in RF test equipment,
antenna systems, and satellite communication systems. Additionally, their high performance and reliability
make them widely utilized in military and aerospace applications, including radar systems, navigation
equipment, and communication systems. The introduction of this series of products is expected to bring broader
application prospects and technological innovation to related industries.
Key Features & Advantages
- Broadband Operation:
- Covers an octave or wider frequency range (e.g., 2-4GHz, 6-18GHz), capable of replacing multiple narrowband circulators, simplifying system design.
- Compact Size & Light Weight:
- Utilizes a planar microstrip structure, eliminating bulky metal cavities and waveguides. Significantly smaller and lighter than traditional circulators, ideal for applications with strict space and weight constraints.
- High Integration:
- Surface mount or direct microstrip line bonding facilitates easy integration with other microwave circuits (e.g., amplifiers, filters, mixers) on a PCB, simplifying system assembly.
- Excellent High-Frequency Performance:
- Low Insertion Loss: Ensures minimal signal power loss during forward transmission.
- High Isolation: Effectively prevents signal reverse transmission, protecting sensitive upstream components (e.g., power amplifiers).
- High Return Loss: Good port matching results in low reflection, ensuring system stability.
- High Reliability & Stability:
- All-solid-state design, no moving parts, resistant to vibration and shock.
- Stable performance over temperature, operable within a wide temperature range.
- Cost-Effectiveness:
- Suitable for standardization and mass production, relatively low manufacturing cost, offering high value.
Typical Applications
Broadband microstrip circulators are widely used in modern electronic systems requiring efficient spectrum utilization and signal management:
- Radar Systems:Used in Transmit/Receive (T/R) modules to enable a single antenna to be shared by the transmitter and receiver, isolating the high-power transmit signal from the sensitive receiver.
- Communication Systems:
- Base Stations: Separate transmit and receive signals in TDD systems.
- Satellite Communication: Transmit-receive switching in both satellite payloads and ground stations.
- Electronic Warfare (EW):Used for signal routing and channel switching in reconnaissance and jamming equipment.
- Test & Measurement:A key component in test equipment like Vector Network Analyzers (VNAs) to protect the signal source.
- Microwave Radio:Used as diplexers in point-to-point communication links.
