Overview
The ZX75BP-135-S+ is a ruggedized bandpass filter from Mini-Circuits designed for radio frequency applications. It operates with a center frequency of 135 MHz and a bandwidth of 30 MHz, covering the 120 MHz to 150 MHz range. The component features an insertion loss of 3.5 dB and supports a power handling capability of 27 dBm. It utilizes SMA connectors in an inline configuration and maintains a standard impedance of 50 Ohms. The physical dimensions are approximately 18.80 mm in length, 19.05 mm in width, and 12.45 mm in height.
Feature Summary
- Ruggedized connectorized package construction
- High power handling capability
- Low insertion loss design
Applications
- RF signal conditioning
- Frequency selection in communication systems
- Interference rejection in receiver front-ends
Procurement Notes
Verify the specific part number suffix against official Mini-Circuits documentation to ensure compatibility with required interface standards. Confirm that the SMA connector type matches system requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating frequency range aligns with the specified 120 MHz to 150 MHz passband for optimal performance.
Selection Notes
Select this component when a ruggedized solution is required for high-power RF environments at 135 MHz. The 50 Ohm impedance ensures compatibility with standard transmission lines. Consider the physical size constraints as it is a standalone module rather than a surface-mount device. Evaluate the 27 dBm power rating against maximum expected signal levels to prevent damage.
Part Context
This model belongs to the ZX75BP series, which focuses on robust, connectorized RF filters. The series is engineered for durability in demanding conditions. The ZX75BP-135-S+ specifically targets the VHF band. It complements other models in the lineup by offering specialized frequency coverage with high power tolerance.
Replacement Considerations
Consult Mini-Circuits documentation for direct substitutes within the ZX75BP series. Verify that alternative parts match the 135 MHz center frequency and 30 MHz bandwidth. Ensure replacement components maintain the same SMA interface and 50 Ohm impedance characteristics.
