Overview
The CBP4-3180AG+ is a surface mount ceramic resonator bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 3.126 GHz to 3.234 GHz, centered at 3.18 GHz. The device features a nominal impedance of 50 Ohms and an insertion loss of 1.5 dB typical. It provides high rejection of 70 dB typical and supports fractional bandwidths from less than 1% to 25%. The component utilizes rugged construction suitable for demanding environments.
Feature Summary
- Utilizes rugged ceramic resonator construction for durability
- Provides high signal rejection capabilities
- Designed for low profile surface mount integration
Applications
- S-band upconverter assemblies
- RF signal conditioning circuits
- Wireless communication systems
Procurement Notes
Verify the specific part number against official Mini-Circuits documentation to confirm electrical characteristics and physical dimensions. Ensure compatibility with the target PCB layout and operating temperature range. Confirm that the 50 Ohm impedance matches the system requirements. Check for any specific handling instructions related to the ceramic resonator technology.
Selection Notes
Select this component when a narrowband filter is required around the 3.18 GHz center frequency. Consider its low insertion loss and high rejection specifications for applications requiring precise signal isolation. Evaluate the fractional bandwidth needs against the available options from less than 1% to 25%. Ensure the surface mount package fits the design constraints.
Part Context
This component belongs to the CBP series of coaxial-ceramic resonator filters from Mini-Circuits. These filters are designed for passbands ranging from DC up to 6 GHz. The series offers various fractional bandwidth options and maintains a low profile design suitable for modern electronic assemblies.
Replacement Considerations
Consult Mini-Circuits documentation for direct substitutes within the CBP series or other compatible ceramic resonator filters. Verify that alternative parts match the 3.126–3.234 GHz frequency range and 50 Ohm impedance.
