BP0805A4320ASTR500

Overview

The KYOCERA AVX BP0805A4320ASTR500 is a surface-mount bandpass RF filter designed for signal conditioning applications. It operates at a center frequency of 4.32 GHz with a bandwidth of 400 MHz. The component features a 50-ohm impedance and supports up to 5 watts of power handling. Housed in an 0805 (2012 metric) package, it offers low insertion loss of 1.2 dB. The device functions within a temperature range of -40°C to +85°C and utilizes SMD/SMT termination types.

Feature Summary

• Provides high-performance bandpass filtering with steep roll-offs for out-of-band rejection
• Engineered for low insertion loss to maintain signal integrity in RF circuits
• Compact 0805 surface-mount footprint suitable for space-constrained designs

Applications

• Wireless communication systems requiring precise frequency selection
• RF front-end modules for base stations and access points
• Signal conditioning in microwave and millimeter-wave equipment

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging quantity and reel specifications. Ensure the part number matches the required center frequency and bandwidth parameters for your design. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders.

Selection Notes

Select this component when a 4.32 GHz center frequency with 400 MHz bandwidth is required. Consider the 0805 package size for board layout constraints. Evaluate the 5W power handling capability against system requirements. Verify compatibility with 50-ohm system impedance and operating temperature ranges from -40°C to +85°C.
