ZX75BP-440-S+

Overview

The ZX75BP-440-S+ is a lumped LC bandpass filter from the ZX75BP series, designed for RF signal conditioning. It operates with a center frequency of 440 MHz and a bandwidth of 60 MHz. The device features SMA connectors and maintains a 50 Ohm impedance. It supports an input power of 0.5W at 25°C and exhibits a maximum insertion loss ranging from 1.8dB to 4dB. The unit is rated for operation between -40°C and +85°C.

Feature Summary

• Provides improved impedance matching within the passband
• Utilizes lumped LC circuit topology for compact design
• Offers high attenuation in stopbands to suppress interference

Applications

• RF front-end filtering in communication systems
• Signal conditioning in test and measurement equipment
• Interference suppression in wireless infrastructure

Procurement Notes

Verify the specific datasheet revision and electrical characteristics against current Mini-Circuits documentation before integration. Confirm that the SMA connector polarity and mating requirements align with system interface specifications. Ensure thermal management strategies accommodate the specified operating temperature range and power handling limits during final assembly.

Selection Notes

Select this component when a narrow 60 MHz bandwidth centered at 440 MHz is required. The lumped LC design offers a compact alternative to ceramic resonators. Verify compatibility with 50 Ohm system impedance and ensure the 0.5W power rating meets application demands without derating issues.

Part Context

This part belongs to the ZX75BP series of lumped LC bandpass filters manufactured by Mini-Circuits. The series provides various center frequencies and bandwidths using similar construction methods. These filters are engineered for general-purpose RF applications requiring reliable signal selection and noise rejection in constrained spaces.
