AM978B993

Overview

The AM978B993 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 978 MHz with a bandwidth defined as FO +/- 5 MHz. The component features a 50 Ohm input and output impedance, ensuring compatibility with standard RF systems. Designed for monoblock construction, it utilizes two PC pads for mounting. This filter is engineered to provide precise signal selection in the specified frequency range, maintaining signal integrity through controlled insertion loss characteristics typical of ceramic resonator technology.

Feature Summary

• Monoblock ceramic construction for structural stability
• Bandpass filtering capability centered at 978 MHz
• Standard 50 Ohm impedance matching

Applications

• RF signal processing circuits
• Wireless communication systems operating near 978 MHz
• Test and measurement equipment requiring specific frequency isolation

Procurement Notes

Verify the exact center frequency and bandwidth specifications against the official manufacturer datasheet before integration. Confirm that the 50 Ohm impedance matches your system requirements. Ensure the monoblock package style and PC pad mounting configuration are compatible with your PCB layout. Cross-reference the part number AM978B993 with current Anatech Electronics documentation to confirm availability and any potential design changes.

Selection Notes

Select this component when a fixed center frequency of 978 MHz is required with a narrow bandwidth tolerance. The 50 Ohm impedance makes it suitable for standard RF interfaces. Consider the physical dimensions and mounting style if space constraints exist. Evaluate insertion loss requirements against the datasheet specifications to ensure signal attenuation meets system performance goals.
