SAC3518

RF Mixers Overview

The SAC3518 is a GaAs MMIC subharmonic mixer designed for high-frequency RF applications. It operates with an RF frequency range of 18 to 36 GHz and a local oscillator (LO) frequency of 9 to 16 GHz, utilizing second-order mixing. The intermediate frequency (IF) output spans from DC to 7 GHz. The device exhibits a typical conversion loss of -13 dB. Delivered as a bare die, the component minimizes parasitic effects to enhance RF performance, requiring specialized assembly techniques due to its exposed configuration.

RF Mixers Feature Summary

• Subharmonic mixing architecture enabling lower LO drive requirements
• GaAs MMIC construction for optimized high-frequency operation
• Bare die format to minimize parasitic inductance and capacitance

RF Mixers Applications

• VSAT up-converters
• Point-to-point microwave radio links
• Satellite communication ground stations

RF Mixers Procurement Notes

Verify that the procurement source provides the component as a bare die rather than a packaged module. Confirm handling protocols for unencapsulated semiconductor dies are available. Ensure the supplier offers traceability documentation consistent with SuperApex, LLC manufacturing standards. Check for compatibility with flip-chip or wire-bonding assembly processes required for this specific form factor.

RF Mixers Selection Notes

Select this component when designing systems requiring direct up-conversion from 9-16 GHz LO to 18-36 GHz RF bands. The bare die format necessitates careful PCB layout and mounting considerations compared to packaged alternatives. Evaluate thermal management strategies suitable for exposed die implementations. Ensure the system can support the required IF bandwidth up to 7 GHz.
