F1792NLGI8

RF Mixers Overview

The F1792NLGI8 is a wideband, gain-settable downconverting mixer manufactured by Renesas Electronics. It operates within an RF range of 400 MHz to 3800 MHz and an LO range of 400 MHz to 3600 MHz. The intermediate frequency (IF) range spans from 50 MHz to 600 MHz. The device provides four discrete gain settings: 11 dB, 8 dB, 5 dB, and 2 dB, controlled via a 2-bit interface. It features a third-order output intercept point (OIP3) of +35 dBm and utilizes FlatNoise technology for low noise figure performance across all gain states. The component is housed in a 24-pin TQFN package measuring 4 mm x 4 mm.

RF Mixers Feature Summary

• Supports wideband operation with independent RF, LO, and IF frequency ranges suitable for multi-carrier systems
• Offers four selectable gain levels managed through a simple 2-bit digital control interface
• Integrates FlatNoise technology to maintain consistent low noise figure regardless of the selected gain setting

RF Mixers Applications

• Multi-carrier communication systems requiring flexible gain adjustment
• Wideband receiver front-ends utilizing direct conversion or low-IF architectures
• Software-defined radio platforms needing high linearity and fast settling times

RF Mixers Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing this component. Confirm that the supply chain adheres to moisture sensitivity level requirements during storage and handling. Ensure compatibility with the required evaluation board accessories if initial testing is planned. Cross-reference the manufacturer's latest product change notifications to confirm assembly location and material set consistency before finalizing procurement orders.

RF Mixers Selection Notes

Select this component when designing systems that require broad frequency coverage without multiple part numbers for different bands. The integrated impedance matching simplifies schematic design by eliminating external matching networks for RF, LO, and IF ports. Consider the power consumption characteristics relative to the thermal constraints of the 4 mm x 4 mm package. Evaluate the 75 nsec settling time against the system's requirement for rapid gain switching between channels.

RF Mixers Part Context

This device belongs to the VersaMixer family of wideband mixers designed for high-performance analog signal processing. It replaces older discrete mixer solutions by integrating passive components and biasing circuits into a single surface-mount package. The architecture supports both single-ended and balanced interfaces, providing flexibility for various system topologies while maintaining a small footprint.

RF Mixers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Designers should evaluate other Renesas VersaMixer variants for pin-to-pin compatibility or functional equivalence. Verify that alternative components support the same 400 MHz to 3800 MHz RF range and offer comparable OIP3 specifications.
