1720BL15B0050002E

Overview

The 1720BL15B0050002E is a wideband ceramic balun manufactured by Johanson Technology Inc. It operates within a frequency range of 625 MHz to 2.815 GHz, providing a 1:1 impedance ratio. The component utilizes a 50 Ohm balanced to 50 Ohm unbalanced configuration. It is designed for surface mount technology (SMD/SMT) applications and is housed in an EIA 0805 package, equivalent to the 2012 metric size.

Feature Summary

• Provides wideband signal conversion between balanced and unbalanced circuits across a broad frequency spectrum.
• Utilizes ceramic construction for stable performance in RF signal conditioning applications.
• Features a compact 0805 surface mount footprint suitable for space-constrained PCB designs.

Applications

• Wireless LAN systems operating in the 2.4 GHz band
• Bluetooth low energy transceivers
• Zigbee and other IEEE 802.15.4 based wireless protocols

Procurement Notes

Verify the specific suffix '002E' against official Johanson Technology documentation to confirm current manufacturing status and pinout compatibility. Ensure that the 1:1 impedance ratio requirement aligns with the target circuit design before procurement. Cross-reference the datasheet for precise electrical tolerances and thermal specifications relevant to the final assembly environment.

Selection Notes

Select this component when a wideband solution covering both sub-GHz and 2.4 GHz ISM bands is required within a single device. The 1:1 ratio makes it suitable for direct interface with differential RF ports without impedance transformation. Consider the 0805 package size relative to available board real estate and thermal dissipation requirements for the specific application.

Part Context

This part belongs to the BL series of wideband ceramic baluns from Johanson Technology. These components are engineered for high reliability in consumer electronics and IoT devices. The series offers various impedance ratios and frequency ranges, with this specific model focusing on the overlap between lower UHF frequencies and the primary Wi-Fi/Bluetooth band.
