ZX75BP-400-S+

Overview

The ZX75BP-400-S+ is a connectorized bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 292 MHz to 490 MHz, centered at 391 MHz with a bandwidth of 198 MHz. The device features a 50 Ohm impedance and utilizes SMA connectors for inline installation. It provides typical stopband rejection of 30 dB and supports an input power level of 27 dBm.

Feature Summary

• Provides high signal rejection in the stopband while maintaining good impedance matching within the passband.
• Utilizes a robust connectorized package design for reliable inline integration into RF systems.

Applications

• RF signal conditioning
• Frequency selection in communication systems
• Interference filtering

Procurement Notes

Verify the specific SMA connector gender (female/male) configuration required for your system interface before ordering. Confirm that the 27 dBm power handling capability aligns with your application's maximum signal levels. Ensure the 50 Ohm impedance matches your transmission line requirements to maintain optimal performance and minimize reflections.

Selection Notes

Select this component when a fixed center frequency of 391 MHz is required. It is suitable for applications needing moderate bandwidth coverage between 292 MHz and 490 MHz. Consider its connectorized form factor if board-mount alternatives are not feasible for your assembly process.
