LTC5569IUF#PBF

RF Mixers Overview

The LTC5569IUF#PBF is a dual active down-converting mixer IC manufactured by Analog Devices Inc. It operates within a frequency range of 300MHz to 4GHz and utilizes a 16-QFN (4x4) package with an exposed pad. The device requires a 3.3V power supply and draws 180mA of current. Key electrical specifications include a noise figure of 11.7dB, a gain of 2dB, and it supports surface mount installation. This component is designed for general-purpose RF applications.

RF Mixers Feature Summary

• Dual active down-conversion architecture
• Internal impedance matching for RF and LO ports
• Integrated bandpass network at IF output

RF Mixers Applications

• Evaluation using DC1719A demonstration circuit
• RF signal chain down-conversion
• General purpose mixer applications

RF Mixers Procurement Notes

Verify the specific ordering suffix #PBF to confirm lead-free compliance and tube packaging configuration. Ensure the procurement request matches the exact manufacturer part number to avoid confusion with alternative packages or non-compliant variants. Cross-reference the distributor catalog number DC1719A-ND only if acquiring the associated evaluation board, not the IC itself.

RF Mixers Selection Notes

Select this component when a dual mixer solution is required for frequencies up to 4GHz. The 16-QFN package suits space-constrained designs. Verify that the system can accommodate the 180mA current draw and 3.3V supply requirement. Consider the 11.7dB noise figure performance relative to system sensitivity needs.

RF Mixers Part Context

This IC belongs to the LTC5569 family of active mixers from Analog Devices. It is distinct from the LT5571 series, which are modulators. The device is often evaluated using the dedicated DC1719A demo board, which provides optimized port matching for testing purposes.
