DEA252593BT-2074A3

Overview

The DEA252593BT-2074A3 is a surface-mount LTCC bandpass filter manufactured by TDK Corporation. It operates within the 2496 MHz to 2690 MHz frequency range, centered at 2593 MHz with a bandwidth of 194 MHz. The component features a center frequency insertion loss of 1.7 dB and utilizes a 1008 (2520 Metric) package measuring 2.5 mm by 2.0 mm.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable RF performance
• Provides signal conditioning through bandpass filtering capabilities
• Designed for compact surface-mount integration in wireless devices

Applications

• Wi-Fi connectivity modules
• Bluetooth transceivers
• Smartphone radio frequency sections
