1720BL15A0100001E

Overview

The 1720BL15A0100001E is a wideband ceramic balun manufactured by Johanson Technology Inc. It operates within a frequency range of 625 MHz to 2.8 GHz and features a 1:2 impedance ratio, converting between 50 Ohm single-ended and 100 Ohm balanced ports. The component utilizes an EIA 0805 surface-mount package with SMD/SMT termination. Key electrical specifications include an insertion loss of 1.5 dB and a power handling capacity of 2 W. It supports board mounting and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides wideband signal conversion between single-ended and balanced RF paths
• Utilizes compact ceramic construction for reliable high-frequency performance
• Designed for direct integration into standard surface-mount assembly processes

Applications

• Wireless LAN (WLAN) transceiver circuits
• Bluetooth module interface stages
• Zigbee and other low-power wireless sensor networks
• ISM band communication devices

Procurement Notes

Verify the specific suffix '001E' against current manufacturer documentation to confirm compliance with RoHS standards and material composition. Ensure that the ordering information matches the latest approved part number revision, as Johanson Technology may update identifiers without changing functional characteristics. Cross-reference the datasheet for any updates regarding lead times or packaging configurations before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth covering sub-1 GHz to 2.8 GHz is required in a minimal footprint. The 1:2 impedance transformation suits applications connecting 50 Ohm sources to 100 Ohm differential loads. Consider the 0805 package size for space-constrained designs and verify that the 2 W power rating meets the system's maximum output requirements without thermal derating issues.

Part Context

This device belongs to the BL series of wideband baluns from Johanson Technology. It serves as a passive signal conditioning element within RF front-end architectures. The component replaces discrete transformer implementations, offering improved consistency and reduced board area compared to traditional wound components in modern wireless hardware designs.

Replacement Considerations

The 1720BL15A0100001E is functionally equivalent to the base model 1720BL15A0100. Verify compatibility with the 1720BL15A0100E variant, noting that suffixes may indicate specific packaging or revision changes rather than electrical differences.
