ABF-7R75G+

Overview

The ABF-7R75G+ is a surface-mount thin-film band pass filter designed for RF applications. It operates within a frequency range of 6300 to 9200 MHz, centered at 7.75 GHz. The component features a 50 Ohm impedance and offers an insertion loss of less than 2.5 dB. It utilizes a UC2731 case style with SMD/SMT termination. The filter provides a bandwidth of 2.9 GHz and has a maximum height of 0.090 inches (2.29 mm).

Feature Summary

• Thin-film construction on alumina substrate for low insertion loss and high rejection.
• Surface mount design suitable for automated assembly processes.
• Fixed center frequency operation optimized for specific RF bands.

Applications

• Wireless communication systems requiring signal conditioning.
• RF front-end modules in transceivers.
• Test and measurement equipment filtering.

Procurement Notes

Verify the exact datasheet version from Mini-Circuits before integration. Confirm that the UC2731 package dimensions match your PCB footprint. Ensure the operating environment does not exceed the specified thermal limits. Check for RoHS compliance status if required by your manufacturing standards. Validate impedance matching networks against the provided S-parameter data.

Selection Notes

Select this component when a fixed band pass response between 6.3 and 9.2 GHz is required. Consider the thin-film technology for superior stability compared to discrete LC designs. Evaluate the insertion loss specification against system noise budget requirements. Ensure the surface mount form factor fits the available board space constraints.
