Procurement Notes

Verify the specific suffix 'H' in the part number ZFL-1200GH+ against official Mini-Circuits documentation to confirm the exact variant specifications. Ensure that the ordering details match the required gain control characteristics and package type. Cross-reference the datasheet revision date to ensure access to the most current electrical performance curves and operational limits before procurement.

Selection Notes

Select this component for applications requiring broad frequency coverage from 10 MHz to 1.2 GHz with adjustable amplification. The 60 dB gain control range allows for significant signal level adjustment. Consider the 15 V supply requirement and 230 mA current consumption when designing the power management circuitry. The rugged shielded case is suitable for environments requiring electromagnetic interference protection.

Part Context

The ZFL-1200GH+ belongs to the ZFL series of coaxial low noise and broadband amplifiers by Mini-Circuits. This series is characterized by its robust shielded construction and wideband performance. The ZFL-1200G+ is a related broadband amplifier model within the same family, sharing similar physical and operational characteristics but potentially differing in specific gain control implementations or detailed electrical parameters.

Replacement Considerations

The ZFL-1200G+ is a documented broadband amplifier from Mini-Circuits that may serve as a functional alternative. Verify compatibility regarding the specific gain control voltage requirements and precise frequency response curves. Ensure that the substitute part meets the same 10 MHz to 1.2 GHz operational bandwidth and shielding standards.
