LTC5567
300MHz to 4GHz Active
Downconverting Mixer with
Wideband IF
Features Description n n n n n n n n n The LTCВ®5567 is optimized for RF downconverting mixer
applications that require wide IF bandwidth. The part is
also a pin-compatible upgrade to the LT5557 active mixer,
offering higher linearity and 1dB compression, wider
bandwidth, and lower output spurious levels. Integrated
RF and LO transformers and LO buffer amplifiers allow a
very compact solution. High IIP3: +26.9dBm at 1950MHz
1.9dB Conversion Gain
Low Noise Figure: 11.8dB at 1950MHz
16.5dB NF Under 5dBm Blocking
Low Power: 294mW
Wide IF Frequency Range Up to 2.5GHz
LO Input 50О© Matched when Shutdown
