CBP-1880E+

Overview

The CBP-1880E+ is a ceramic-coaxial-resonator based bandpass filter designed for surface mount technology. It operates at a center frequency of 1.88 GHz with a bandwidth of 200 MHz and an impedance of 50 Ohms. The device features low passband insertion loss and excellent rejection characteristics within a low-profile shielded package measuring 0.638 inches by 0.434 inches by 0.105 inches.

Feature Summary

• Utilizes ceramic-coaxial-resonator technology for stable signal filtering
• Enclosed in a low-profile shielded package to minimize interference
• Engineered for low passband insertion loss and high out-of-band rejection

Applications

• RF signal conditioning circuits
• Wireless communication systems requiring 1.88 GHz filtering
• Industrial control equipment operating at microwave frequencies

Procurement Notes

Verify the specific suffix E+ against official Mini-Circuits documentation to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with standard SMT assembly processes given the specified package dimensions. Cross-reference the 50 Ohm impedance requirement with system design specifications to prevent signal reflection issues during integration.

Selection Notes

Select this component when a fixed center frequency of 1.88 GHz is required with a 200 MHz bandwidth. The shielded SMD package makes it suitable for dense PCB layouts where electromagnetic interference must be contained. Verify that the operational temperature range meets the environmental requirements of the target application before finalizing the bill of materials.
