3550LP14B0500001T

Overview

The Johanson Technology 3550LP14B0500001T is a low-pass filter operating at a center frequency of 3.55 GHz with a bandwidth from 3300 MHz to 3800 MHz. It features a maximum insertion loss of 0.55 dB and a minimum return loss of 11.7 dB. The device provides attenuation of 35 dB at twice the cutoff frequency and 25 dB at three times the cutoff frequency. It operates within a temperature range of -40°C to +85°C, supports a maximum input power of 2 Watts, and utilizes a 50 Ohm impedance in an SMD package.

Feature Summary

• Provides high-frequency signal filtering with specified attenuation characteristics at harmonic frequencies
• Designed for board mounting with surface mount technology termination
• Operates reliably across a wide industrial temperature range

Applications

• RF front-end modules requiring low-pass filtering
• Wireless communication systems operating near 3.55 GHz
• Signal conditioning circuits for high-frequency applications

Procurement Notes

Verify the specific suffix requirements against official Johanson Technology documentation to ensure correct termination style and compliance standards. Confirm that the 2 Watt maximum input power rating aligns with your system's peak power levels. Ensure the 50 Ohm impedance matches your circuit design. Check for any specific handling or storage humidity requirements during manufacturing.

Selection Notes

Select this component when a low-pass filter centered at 3.55 GHz is required with minimal insertion loss. Consider the 0603 package size for space-constrained designs. Evaluate the thermal performance within the -40°C to +85°C range. Compare attenuation specs at 2x and 3x cutoff frequencies against system interference requirements.

Part Context

This part belongs to Johanson Technology's high-frequency ceramic solutions portfolio. It is designed for RF applications requiring precise filtering. The BP and LP series indicate bandpass and low-pass filter families respectively. This specific model focuses on low-pass filtering capabilities for the 3.55 GHz band.

Replacement Considerations

Check for direct substitutes like 3550LP14A0300001T if lead times differ, but verify parameter compatibility. Ensure any replacement maintains the 3.55 GHz center frequency and similar attenuation profiles.
