Overview
The DEA211898BT-9033B1 is a multilayer bandpass filter manufactured by TDK Corporation using low-temperature co-fired ceramic (LTCC) technology. Designed for balanced output applications, this component operates within a frequency range of 729MHz to 2690MHz, specifically targeting the 869-960MHz and 1805-2025MHz bands. It features an LGA terminal shape with dimensions of 2.0mm length, 1.5mm width, and a maximum height of 1.20mm. The device provides low insertion loss and low latency performance, supporting EMI/RFI suppression in communication systems.
Feature Summary
- Utilizes LTCC technology for enhanced signal integrity
- Provides balanced output filtering capability
- Supports dual-band operation across specified RF ranges
Applications
- EMI/RFI suppression in wireless communication devices
- Power line filtering for RF circuits
- Balanced output filtering in mobile terminals
Procurement Notes
Verify the specific ordering suffix against official TDK documentation to ensure compatibility with required termination styles and environmental ratings. Confirm that the LTCC construction meets the thermal management requirements of the target assembly process. Cross-reference the LGA package dimensions with PCB footprint specifications to prevent mechanical interference during placement.
Selection Notes
Select this component when balanced filtering is required for frequencies between 869MHz and 2025MHz. The LTCC construction offers advantages in size reduction compared to discrete solutions. Ensure the application environment supports the operating temperature range specified in the datasheet. Evaluate insertion loss characteristics against system sensitivity requirements before finalizing the design.
Part Context
