High Signal Level Active

Downconverting Mixer

FeaTures

DescripTion

The LTC^®5577 active mixer is optimized for RF downcon-

vertingapplicationsthatrequirehighinputsignalhandling

capabilityandwidebandwidth.ThewidebandIFoutputuses

external resistors to set the output impedance, allowing

the flexibility to match directly into differential IF loads,

such as filters and amplifiers. The part is characterized

and specified with a 100Ω differential output impedance,

although it can be used with output impedances ranging

from 50Ω to 400Ω, with higher gain and reduced IIP3

and P1dB at the higher impedance levels. The IF output

is usable up to 1.5GHz.

Wideband Differential IF Output

Very Low 2 × 2 and 3 × 3 Spurs

IF Frequency Range Up to 1.5GHz

Low LO-RF Leakage

–40°C to 105°C Operation (T )

Very Small Solution Size

16-Lead (4mm × 4mm) QFN package

Inreceiverapplications,thehighinputP1dBandIIP3allow

the use of higher gain low noise amplifiers, resulting in

higher receiver sensitivity. Integrated transformers on the

RF and LO inputs provide single-ended 50Ω interfaces,

while minimizing the solution size.
