Overview
The ZX75BP-130-S+ is a lumped LC bandpass filter from Mini-Circuits designed for RF signal conditioning. It operates within a frequency range of 95 to 180 MHz, with a center frequency of 137.5 MHz and a bandwidth of 85 MHz. The component features a 50 Ohm impedance and SMA connectors. Key electrical specifications include a maximum insertion loss of 2.5 dB, typical stopband rejection of 30 dB, and typical stopband return loss of 14 dB. It supports up to 24 dBm power handling and functions reliably between -40°C and +85°C.
Feature Summary
- Utilizes lumped LC topology for compact bandpass filtering
- Provides high stopband rejection capabilities
- Features low insertion loss for efficient signal transmission
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 version for precise attenuation curves and thermal derating information. Confirm connector polarity and mating compatibility with existing SMA interfaces. Ensure environmental ratings meet operational temperature requirements. Cross-reference part numbers to avoid confusion with similar series components.
Selection Notes
Select this model when a narrow bandpass response around 137.5 MHz is required. Consider the 2.5 dB insertion loss impact on system noise figure. Evaluate physical dimensions against PCB or chassis constraints. Verify power handling limits relative to expected signal levels.
Part Context
This component belongs to the ZX75BP series of lumped LC bandpass filters. The series offers various center frequencies and bandwidths tailored for different RF applications. Mini-Circuits manufactures these devices using established thin-film and lumped element technologies for consistent performance.
Replacement Considerations
Direct substitutes may include other ZX75BP variants with adjusted frequency parameters. Verify that alternative components match the 50 Ohm impedance and SMA interface. Check if replacement parts offer comparable insertion loss and rejection characteristics.
