ZX75-12M-S+

Overview

The ZX75-12M-S+ is a connectorized bandpass filter from Mini-Circuits, designed for RF applications. It operates with a center frequency of 12 MHz and a bandwidth of 6 MHz, covering a passband range of 9 to 15 MHz. The component features a 50 Ohm impedance and utilizes SMA connectors for inline mounting. Key electrical specifications include an insertion loss of 3.5 dB. This device is part of the ZX75 series, providing signal conditioning in the low-frequency RF spectrum.

Feature Summary

• Provides selective frequency filtering within the 9 to 15 MHz passband
• Maintains 50 Ohm system impedance for standard RF integration
• Utilizes SMA connectors for direct inline circuit connection

Applications

• RF signal conditioning circuits
• Frequency selection in communication systems
• Interference rejection in low-frequency RF environments

Procurement Notes

Verify the specific datasheet version and electrical performance graphs directly from Mini-Circuits or authorized distributors before finalizing design integration. Confirm that the SMA connector type and inline mounting style align with your PCB or chassis requirements. Ensure environmental ratings meet operational temperature expectations.

Selection Notes

Select this component when a fixed 12 MHz center frequency with a 6 MHz bandwidth is required. The 3.5 dB insertion loss should be evaluated against system sensitivity limits. The inline form factor suits applications where space allows for free-hanging installation rather than surface-mount constraints.

Part Context

This model belongs to the ZX75 series of connectorized filters manufactured by Mini-Circuits. The series covers various frequency ranges using lumped LC or ceramic resonator technologies. The ZX75-12M-S+ specifically addresses the 9-15 MHz band, distinguishing it from higher-frequency variants in the same product family.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers must evaluate alternative 12 MHz bandpass filters based on identical impedance, connector type, and insertion loss specifications if substitution is necessary.
