n 16-Lead (4mm Г— 4mm) QFN package The LTCВ®5577 active mixer is optimized for RF downconverting applications that require high input signal handling
capability and wide bandwidth. The wideband IF output uses
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 100О© differential output impedance,
although it can be used with output impedances ranging
from 50О© to 400О©, with higher gain and reduced IIP3
and P1dB at the higher impedance levels. The IF output
is usable up to 1.5GHz. In receiver applications, the high input P1dB and IIP3 allow
the use of higher gain low noise amplifiers, resulting in …
