RFBPF3225180C07B1U

Overview

The RFBPF3225180C07B1U is a multilayer ceramic bandpass filter manufactured by Walsin Technology Corporation. It utilizes Low-Temperature Co-fired Ceramics (LTCC) technology and features a miniature 1210 (3225 metric) surface-mount package with a 3-pad configuration. The component operates within the 1125 MHz to 1675 MHz frequency range, centered at 1.4 GHz, with a bandwidth of 550 MHz. It exhibits an insertion loss of 1.8 dB and supports standard 50Ω or 75Ω impedance configurations for RF signal conditioning.

Feature Summary

Procurement Notes

Verify the specific impedance requirement (50Ω or 75Ω) against the target circuit design before procurement, as datasheet specifications may vary by suffix. Confirm that the 1210 footprint aligns with the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a low-profile bandpass filter is required for frequencies between 1125 MHz and 1675 MHz. The LTCC construction offers stability suitable for high-frequency applications. Consider the 1.8 dB insertion loss impact on system gain. The 1210 package size balances performance with space efficiency for dense PCB layouts.
