SFM2018

RF Mixers Overview

The SFM2018 is an RF mixer manufactured by Fairview Microwave, designed for signal conversion applications within the radio frequency spectrum. This component operates with an RF frequency range spanning from 2 GHz to 18 GHz. It features a local oscillator (LO) frequency range that also covers 2 GHz to 18 GHz, ensuring compatibility across the specified band. The intermediate frequency (IF) output range extends from DC to 2 GHz, allowing for effective down-conversion or up-conversion tasks. The device requires a local oscillator power input of +10 dBm to function optimally. A maximum conversion loss of 11 dB is specified, indicating the signal attenuation during the mixing process. The connector interface utilizes SMA female ports, providing standard connectivity for RF test and measurement setups.

RF Mixers Procurement Notes

Verify the specific datasheet version and connector gender details before procurement, as distributor listings may vary in description accuracy. Confirm that the required LO power level of +10 dBm aligns with your system's signal generator capabilities. Ensure SMA female mating components are available for integration. Check for any recent product change notices or obsolescence alerts from Fairview Microwave to ensure long-term availability for your project lifecycle.

RF Mixers Selection Notes

Select the SFM2018 when an RF mixer covering the 2-18 GHz range is required with a low-frequency IF output up to 2 GHz. Consider the 11 dB maximum conversion loss impact on system noise figure and signal-to-noise ratio. Verify that the +10 dBm LO drive requirement fits within your local oscillator's output specifications. Compare against other mixers if higher linearity or lower conversion loss is critical for your specific application performance needs.

RF Mixers Part Context

The SFM2018 belongs to Fairview Microwave's portfolio of RF mixers and multipliers, which are essential components for frequency translation in high-frequency electronic systems. These devices facilitate the interaction between RF, LO, and IF signals. The mixer category supports various configurations for different frequency bands and power levels. This specific model targets applications requiring broad RF bandwidth with standard SMA interfaces, fitting into broader signal conditioning and RF subsystem designs.

RF Mixers Replacement Considerations

No public confirmed substitute part numbers are listed in the provided documentation. Evaluate alternative mixers from Fairview Microwave or other manufacturers based on matching RF/LO frequency ranges, IF bandwidth, connector type, and LO power requirements. Ensure any replacement maintains compatible impedance and physical form factor for existing PCB or cable assemblies.
