FMFL003

Overview

The FMFL003 is a bandpass RF filter manufactured by Fairview Microwave, designed for operation within the 1.565 GHz to 1.585 GHz frequency range with a center frequency of 1.575 GHz and a bandwidth of 20 MHz. It features an insertion loss of 1.5 dB, a voltage standing wave ratio (VSWR) of 1.50:1, and a rejection level of 50 dB. The component supports a power handling capacity of 5 W and utilizes SMA connectors in a module package. Its physical dimensions are 57.20 mm in length, 39.40 mm in width, and 13.50 mm in maximum height.

Feature Summary

• Provides selective signal filtering within the specified 1.565-1.585 GHz band
• Maintains low signal attenuation through minimized insertion loss characteristics
• Ensures impedance matching stability via controlled VSWR performance
• Offers high out-of-band interference suppression with significant rejection levels

Applications

• GNSS receiver front-end signal conditioning
• Satellite navigation system filtering
• RF communication channel isolation

Procurement Notes

Verify the specific SMA connector orientation and mounting configuration against the mechanical drawing before integration. Confirm that the 5 W power rating aligns with the peak and average power requirements of the target application circuit. Ensure the operating temperature range meets environmental specifications. Cross-reference the RoHS3 compliance status if restricted substances are mandated by the end-use industry standards.

Selection Notes

Select this component when precise filtering around the 1.575 GHz center frequency is required. The 20 MHz bandwidth suits applications needing narrowband signal extraction. Consider the module form factor for space-constrained installations. Evaluate the 1.5 dB insertion loss impact on overall system noise figure. Verify compatibility with existing SMA interconnect infrastructure.
