Overview
The DEA102025LT-6313A1 is a multilayer low-pass filter manufactured by TDK Corporation, designed for RF signal conditioning applications. It operates within a center frequency range of 1880 MHz to 2025 MHz, specifically targeting cellular bands 33, 34, and 39. The component features a 40 MHz bandwidth with a maximum insertion loss of 0.5 dB in the passband. It utilizes a 50-ohm single-ended impedance configuration and is housed in a compact 0402 (1005 metric) surface-mount package with four terminals.
Feature Summary
- Multilayer LTCC construction for high reliability and thermal stability
- Optimized attenuation characteristics for specific cellular frequency bands
- Compact 0402 footprint suitable for space-constrained mobile devices
Applications
- Cellular base stations and handsets supporting Band 33/34/39
- WCDMA and GSM/LTE transceiver modules
- IoT devices requiring RF signal filtering
Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure storage conditions meet LTCC component requirements to maintain performance integrity.
Selection Notes
Select this component when designing circuits for LTE Bands 33, 34, or 39 requiring a 50-ohm system impedance. The 0402 package size is critical for dense PCB layouts in smartphones and tablets. Verify that the 0.5 dB insertion loss meets the link budget requirements of the specific application.
Part Context
This component belongs to the TDK DEA10-L series of passive RF filters. These filters are engineered for wireless connectivity solutions, addressing the growing demand for reliable signal conditioning in IoT and mobile communication devices. The series supports various frequency ranges tailored to global cellular standards.
Replacement Considerations
Consult TDK's official substitution guide for compatible alternatives within the DEA series. Ensure any replacement maintains the same 0402 footprint, 50-ohm impedance, and frequency response characteristics for Bands 33/34/39.
