3550LP14A300T/PB

Overview

The Johanson Technology Inc. 3550LP14A300T/PB is a low-pass filter designed for high-frequency applications. It operates within a frequency range of 3400 MHz to 3700 MHz, with a maximum insertion loss of 0.65 dB and a minimum return loss of 11.7 dB. The component provides attenuation of at least 25 dB at three times the center frequency. It features a 50 Ω impedance, supports a maximum input power of 2 Watts, and functions within an operating temperature range of -40°C to +85°C. The device utilizes a surface-mount package with tin/lead-free terminations.

Feature Summary

• Provides signal conditioning through low-pass filtering characteristics in the 3.5 GHz band
• Designed for efficient power handling with a 2-watt maximum input rating
• Constructed with lead-free terminations compliant with environmental standards

Applications

• WiMAX communication systems
• High-frequency RF signal conditioning
• Wireless infrastructure equipment

Procurement Notes

Verify the specific suffix /Pb indicates lead-free compliance as per manufacturer documentation. Confirm the legacy part number 3550LP14A300 corresponds to this variant. Ensure the reel quantity matches project requirements. Check RoHS certification status directly from official datasheets before procurement.

Selection Notes

Select this component for applications requiring low insertion loss in the 3.4-3.7 GHz range. Consider the 50 Ω impedance match for standard RF circuits. Evaluate thermal performance against the -40°C to +85°C operating limit. Compare attenuation specifications against system noise floor requirements.

Part Context

This component belongs to Johanson Technology's general-purpose filter series. It is categorized as a low-pass filter intended for high-frequency ceramic solutions. The product line focuses on compact surface-mount designs suitable for modern electronic devices requiring precise signal filtering.

Replacement Considerations

The legacy part number 3550LP14A300 serves as a direct predecessor. Verify electrical parameters match exactly when substituting. Ensure termination style compatibility remains consistent with existing PCB layouts.
