BLNK1-252R+

Overview

The BLNK1-252R+ is a miniature LTCC transformer designed for RF signal conditioning. It operates within the 2400 MHz to 2500 MHz frequency range with a 50 Ohm impedance. The component features a surface mount SMD/SMT package in a 0402 footprint (1.0mm x 0.5mm x 0.38mm). Electrical specifications include a maximum insertion loss of 1.3 dB, a minimum return loss of 9 dB, and amplitude/phase balance of 0.7 dB and 0.7 degrees respectively. It supports a temperature range from -40°C to +85°C.

Feature Summary

• Miniature 0402 LTCC construction for space-constrained designs
• Balanced-to-unbalanced or balanced-to-balanced conversion capability
• Integrated matching network eliminates external components
• RoHS compliant lead-free manufacturing

Applications

• Wireless LAN modules operating at 2.4 GHz
• Bluetooth transceiver interfaces
• ISM band communication devices
• RF front-end signal conditioning

Procurement Notes

Verify the specific suffix 'R+' indicates RoHS compliance and tape-and-reel packaging configuration. Confirm the manufacturer datasheet revision date matches project requirements. Ensure the ordering part number aligns exactly with the required impedance and frequency specifications. Request batch-specific test reports if critical performance consistency is required for production.

Selection Notes

Select this component when a compact solution is required for 2.4 GHz applications. The integrated design reduces board space compared to discrete transformers. Verify that the 0.7 dB amplitude balance meets system linearity requirements. Consider the thermal characteristics for high-density PCB layouts.

Part Context
