AB4887B1059

Overview

The AB4887B1059 is a cavity bandpass RF filter manufactured by Anatech Electronics Inc. It operates within a passband of 4775-5000 MHz, providing a center frequency of 4887 MHz with a bandwidth of 225 MHz. The component features an insertion loss of ≤1.0 dB and a return loss of ≥15 dB. Rejection performance reaches ≥90 dB at 4700 MHz. It utilizes SMA connectors and is designed for chassis mounting. Physical dimensions are 4.670 inches in length by 3.550 inches in width.

Feature Summary

• High-rejection cavity construction for precise signal filtering
• Low insertion loss design for efficient signal transmission
• Chassis mount configuration for stable integration

Applications

• Military communication systems
• Commercial RF infrastructure
• Microwave signal processing

Procurement Notes

Verify the specific datasheet version (AB4887B1059.pdf) against your technical requirements before ordering. Confirm that the SMA connector type and chassis mounting dimensions align with your enclosure specifications. Ensure the operating temperature range meets your environmental constraints. Cross-reference the part number with official Anatech Electronics documentation to confirm current product status and availability.

Selection Notes

Select this component when a narrow-band cavity filter is required for frequencies near 4.9 GHz. The low insertion loss makes it suitable for sensitive receiver front ends. The high rejection at 4700 MHz provides necessary isolation from adjacent bands. Consider the physical size constraints due to the chassis mount form factor. Verify compatibility with existing SMA interconnects in the system architecture.
