1720BL15B0200001E

Overview

The Johanson Technology Inc. 1720BL15B0200001E is a wideband ceramic RF balun designed for surface-mount applications in the EIA 0805 (2012 metric) package. It operates within a passband frequency range of 625 MHz to 2815 MHz, providing balanced-to-unbalanced signal conversion with a 1:4 impedance ratio. The component features an unbalanced impedance of 50 Ohms and a balanced impedance of 200 Ohms. It supports operation across a temperature range from -40°C to +85°C and is supplied in reel packaging.

Feature Summary

• Provides wideband signal conversion between balanced and unbalanced lines
• Utilizes a compact 0805 surface-mount ceramic construction
• Maintains a fixed 1:4 impedance transformation ratio

Applications

• Wireless LAN (WLAN) transceiver circuits
• Bluetooth and BLE module interfaces
• Zigbee communication systems
• Wi-Fi enabled IoT devices

Procurement Notes

Verify the complete part number including suffixes against official Johanson Technology documentation to ensure correct impedance and frequency specifications. Confirm that the required 0805 footprint aligns with the target PCB layout. Check current supply status as availability may vary by region. Ensure environmental compliance requirements match project standards before finalizing procurement orders.

Selection Notes

Select this component when a wideband solution covering sub-1 GHz through 2.4 GHz bands is required in a minimal footprint. The 1:4 impedance ratio suits direct connection to 50 Ohm unbalanced lines and 200 Ohm balanced loads. Consider thermal performance limits and SMT reflow compatibility during design integration. Evaluate board space constraints relative to the standard 0805 dimensions.

Part Context

This device belongs to Johanson Technology's BL series of wideband ceramic baluns. These components are engineered for high-volume consumer electronics requiring reliable RF signal integrity. The 0805 form factor allows for dense circuit board layouts common in modern portable wireless devices. The series emphasizes consistent electrical performance across broad frequency spans.
