LTC5577IUF

RF Mixers Overview

The LTC5577IUF#PBF is an active down-converter from Analog Devices Inc., designed for RF applications requiring high input signal handling and wide bandwidth. It operates within a radio frequency range of 300 MHz to 6 GHz, with a local oscillator frequency spanning the same band. The intermediate frequency output ranges from 1 MHz to 1.5 GHz. Key electrical parameters include a noise figure of 15 dB, a gain of -0.7 dB, and an OIP3 of 26 dBm. The P1dB compression point is 13.5 dBm. It functions on a supply voltage of 3 V to 3.6 V, drawing 180 mA. The device is housed in a 16-lead QFN (4mm x 4mm) package and supports operating temperatures from -40°C to +105°C.

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm lot traceability and RoHS compliance status prior to integration. Check current lifecycle status as restricted supply may impact long-term availability. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to maintain package integrity before soldering.

RF Mixers Selection Notes

Select this component when design requirements prioritize high linearity and wide dynamic range over low power consumption. The active topology offers superior isolation compared to passive mixers but requires careful thermal management due to 180 mA current draw. Evaluate board space constraints against the 16-lead QFN footprint. Consider external matching networks for the IF port to optimize impedance matching for specific filter requirements.
