AM3550B989

Overview

The AM3550B989 is a monoblock ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 3550 MHz and provides a bandwidth of 500 MHz, covering the range from 3300 to 3800 MHz. The component features a 50-ohm impedance and exhibits an insertion loss of less than 1.3 dB. It offers high attenuation, specified as 40 dB at frequencies between 2300 and 2700 MHz. The device is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Monoblock ceramic construction for structural integrity
• Bandpass filtering capability centered at 3550 MHz
• High out-of-band rejection performance

Applications

• Wireless communication systems requiring 3.3-3.8 GHz filtering
• RF front-end modules in base stations
• Point-to-point microwave links

Procurement Notes

Verify the specific datasheet version provided by Anatech Electronics Inc. or authorized distributors to confirm current manufacturing status and exact electrical tolerances. Ensure that the monoblock package dimensions and pad layout match the target PCB design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a wide 500 MHz bandwidth is required around the 3.55 GHz center frequency. The low insertion loss of under 1.3 dB makes it suitable for applications where signal integrity is critical. Consider the operating temperature range of -40°C to +85°C for environmental compatibility.

Part Context

This part belongs to the family of ceramic bandpass filters produced by Anatech Electronics Inc., which specializes in RF components for wireless infrastructure. These filters are engineered to provide precise frequency selection and noise reduction in high-frequency electronic circuits.

Replacement Considerations

Cross-reference with other Anatech models such as AM3575B1007 if different bandwidth specifications are needed. Verify pinout and mechanical footprint compatibility before substituting with generic equivalents.
