X Band Diplexer

The X Band Diplexer is a key passive microwave component specialized in signal separation and combination within the X-band frequency range. It enables simultaneous transmission and reception of signals through a single antenna, eliminating mutual interference between transmit (Tx) and receive (Rx) channels. Widely applied in radar systems, satellite communication, and electronic countermeasures, the X Band Diplexer is critical for enhancing the integration and operational efficiency of microwave systems.

• High Isolation & Low Insertion Loss: Achieves ≥85 dB Tx-Rx isolation to avoid signal crosstalk, with insertion loss as low as 0.4 dB for minimal signal attenuation.
• Broadband Adaptability: Covers the full 7-9 GHz X-band, supporting flexible customization of Tx/Rx sub-bands to match system requirements.
• High Power Tolerance: Designed to handle 500 W average power and 10 kW peak power, suitable for high-power radar and communication scenarios.

• Advanced Filter Design: Adopts cavity filter structure with precise tuning, ensuring sharp roll-off characteristics and stable frequency response.
• Robust Mechanical Structure: Made of brass with nickel plating, providing excellent corrosion resistance and mechanical stability.
• Compact Size: Miniaturized design for easy integration into limited-space systems (e.g., airborne or shipborne radar).

The X Band Diplexer is widely used in scenarios requiring coaxial Tx/Rx signal management:

• Military Radar Systems: Separates transmit and receive signals in air defense, maritime surveillance, and fire control radars.
• Satellite Communication Terminals: Enables bidirectional communication via a single satellite antenna, reducing system complexity.
• Electronic Countermeasures (ECM): Supports simultaneous jamming (Tx) and signal interception (Rx) in ECM equipment.
• Weather Radar: Facilitates transmission of detection signals and reception of echo signals for meteorological monitoring.

As a professional X Band Diplexer manufacturer, we offer comprehensive OEM solutions:

• Custom Frequency Tuning: Tailor Tx/Rx band ranges, bandwidth, and center frequencies to match specific system designs.
• Connector & Packaging Customization: Provide customized connectors (e.g., TNC, BNC) and packaging (e.g., waterproof enclosures) for special environments.
• Technical Collaboration: Collaborate with customers on thermal design, electromagnetic compatibility (EMC) optimization, and system integration support.

FAQ

Q: How does the isolation of an X Band Diplexer affect system performance?

A: Isolation directly determines signal interference between Tx and Rx channels. High isolation (≥85 dB) prevents transmit signals from overwhelming the receiver, ensuring stable signal reception and avoiding receiver damage.

Q: Can the X Band Diplexer be used in outdoor harsh environments?

A: Yes. Our diplexers use nickel-plated brass and optional waterproof enclosures, enabling reliable operation in -40°C to +55°C, high-humidity, and salt-spray environments (e.g., shipborne or outdoor radar stations).

Q: What factors should be considered when selecting an X Band Diplexer?

A: Key factors include: operating frequency range (matching Tx/Rx bands), insertion loss (lower is better for signal integrity), power handling (matching system transmit power), and connector type (compatible with existing equipment).
