0900BL18B0100001E

Overview

The Johanson Technology Inc. 0900BL18B0100001E is an RF balun designed for the 800MHz to 1GHz frequency range. It operates with a 50 Ohm single-ended port and a 100 Ohm balanced port, facilitating impedance transformation in wireless communication circuits. The component utilizes a surface-mount technology (SMT) package with dimensions of 1206 (3216 Metric). It is rated for a maximum power handling capacity of 3 Watts. This device supports GSM, DCS, PCS, and CDMA protocols, serving as a signal conditioning element for mobile phone applications requiring reliable RF performance within the specified band.

Feature Summary

• Provides impedance matching between 50 Ohm single-ended and 100 Ohm balanced ports
• Supports multiple cellular protocols including GSM, DCS, PCS, and CDMA
• Engineered for high power handling up to 3 Watts
• Utilizes compact 1206 surface-mount packaging for space-constrained designs

Applications

• GSM mobile phone transceivers
• DCS/PCS wireless communication devices
• CDMA handset RF front-ends
• Signal conditioning for 900MHz band applications

Procurement Notes

Verify that the specific order matches the manufacturer part number 0900BL18B0100001E exactly. Confirm the package type is 1206 (3216 Metric) and the frequency range covers 800MHz to 1GHz. Ensure the supplier provides documentation confirming the 3W power rating and 50/100 Ohm impedance configuration. Check for RoHS compliance status if required by your assembly process. Cross-reference the distributor's stock availability against the standard lead time of 17 weeks if applicable.

Selection Notes

Select this component when a balun is required for 900MHz cellular bands with a 50 Ohm to 100 Ohm transformation ratio. It is suitable for applications demanding 3W power handling in a small 1206 footprint. Consider this part for GSM, DCS, PCS, or CDMA implementations where balanced-to-unbalanced conversion is necessary. Evaluate board space constraints against the 1206 SMD size. Ensure the operating temperature range meets the system requirements.
