AB4300B802

Overview

The AB4300B802 is a cavity bandpass RF filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 4.3 GHz and provides a bandwidth of 120 MHz. The component features an insertion loss of 0.8 dB and maintains a standard input/output impedance of 50 Ohms. Designed as a module, it utilizes SMA connectors for interface connectivity. The unit is engineered to withstand mechanical stress, including vibration up to 20 G within the 20 to 200 Hz range and shock resistance defined by a 1 ms half sine wave across three axes in both directions.

Feature Summary

• High-frequency cavity bandpass design optimized for radio frequency applications
• Integrated SMA connectors for standardized module interfacing
• Robust mechanical construction capable of withstanding specified vibration and shock loads

Applications

• Radio frequency signal filtering
• Intermediate frequency processing modules
• RF communication system components

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be hosted on distributor platforms rather than directly on the original manufacturer's site. Confirm that the SMA connector configuration matches the required circuit interface. Ensure the 50 Ohm impedance specification aligns with the surrounding RF chain components to prevent signal reflection issues during integration.

Selection Notes

Select this component when a fixed 4.3 GHz center frequency with 120 MHz bandwidth is required for RF filtering tasks. The 0.8 dB insertion loss indicates efficient signal transmission for this specific frequency range. Consider the physical module form factor and SMA interfaces for compatibility with existing test or production equipment setups requiring rigid cavity filter performance.

Part Context

This part belongs to the family of cavity bandpass filters produced by Anatech Electronics Inc., designed for precise frequency selection in RF environments. Similar models in the series, such as the AE8770B8641 operating at 8770 MHz, demonstrate the manufacturer's focus on high-frequency microwave applications. The AB4300B802 specifically targets the 4.3 GHz range, distinguishing it from lower frequency SAW filters like the AM70S638.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Replacement requires matching the exact 4.3 GHz center frequency, 120 MHz bandwidth, and 50 Ohm impedance specifications. Verify mechanical dimensions and SMA connector orientation before substituting with alternative cavity filters.
