Characteristics and Applications

Key Features & Advantages

1. Low Insertion Loss:
   • Feature: Exceptionally low signal loss in the forward path (Typ. < 0.3 dB).
   • Advantage: Maximizes signal strength, improving system signal-to-noise ratio and efficiency.
2. High Isolation:
   • Feature: Strong suppression of signals in the reverse path (Typ. > 20 dB).
   • Advantage: Effectively prevents transmitted signal leakage into the receive channel, protecting sensitive receivers and reducing system self-interference.
3. High Power Handling Capacity:
   • Feature: Capable of withstanding high average power and high peak power.
   • Advantage: Suitable for demanding applications like radar and high-power communication base stations.
4. Excellent VSWR:
   • Feature: Very low VSWR at all ports (Typ. < 1.20).
   • Advantage: Ensures good impedance matching, minimizes signal reflections, and enhances overall system performance.
5. High Reliability & Stability:
   • Feature: Hermetically sealed structure (laser welding) offers good moisture and salt spray resistance. Wide operating temperature range with minimal performance variation.
   • Advantage: Suitable for harsh environments, ensures long-term stable operation, and extends service life.
6. Compact & Rugged Construction:
   • Feature: Standard coaxial interfaces (e.g., N-type, SMA, TNC), durable metal housing.
   • Advantage: Easy integration into systems, high mechanical strength, withstands vibration and shock.

Typical Applications

1. Radar Systems:
   • Serves as a duplexer, allowing a single antenna to alternately transmit and receive, simplifying system architecture.
2. Wireless Communication Base Stations:
   • Isolates transmit and receive signals between the PA (Power Amplifier) and LNA (Low Noise Amplifier), protecting the receiver from being damaged by the powerful transmitted signal.
3. Test & Measurement Instruments:
   • Provides isolation between a signal source and a load, preventing reflected signals from damaging expensive equipment (e.g., Vector Network Analyzers).
4. Amplifier Protection:
   • Diverts reflected power from the amplifier output to a matched load where it is dissipated, preventing damage to the power amplifier transistor.
5. Other Fields:
   • Microwave relays, satellite communications, electronic warfare (EW), and any scenario requiring control over RF signal direction.
