Key Features and Specifications

• Impedance Options: Available in 50Ω and 75Ω configurations, catering to various system requirements.




• Channel Configurations: Offered in 2-way, 3-way, and 4-way designs, providing flexibility for different circuit layouts.




• Wide Frequency Range: Operates effectively from minimum frequencies as low as 1 MHz to maximum frequencies up to 3250 MHz, ensuring robust performance across low- and high-frequency bands.




• Performance Metrics:
  

• Input Return Loss (RL): Ranges from 5 dB to 38 dB, minimizing signal reflection for efficient power transfer.




• Insertion Loss (IL): Low values from 0.28 dB to 4.5 dB, reducing signal attenuation and enhancing system efficiency.




• Isolation: Provides 12 dB to 35.48 dB of isolation between channels, effectively reducing crosstalk and interference.






• Compact Packaging: Available in multiple package sizes, such as B008, B015, B032, and larger formats like 60x51 mm, accommodating space-constrained designs and diverse installation needs.




• High Current Capacity: Supports saturation currents (Isat) up to 75 A and RMS currents (Irms) up to 57 A, ideal for high-power applications.




• Power over Ethernet (PoE) Support: Select models support PoE-af, PoE-bt (up to 90W), and 4PPoE, with high-voltage isolation options (e.g., 1500VAC/1mA/60s or 5000VAC/1mA/2s) for enhanced safety in power-delivery systems.
