The LTC5577 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 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.In receiver applications, the high input P1dB and IIP3 allow 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.Applications Wireless Infrastructure Receivers DPD Observation Receivers CATV Infrastructure
