Typical applicaTion
FeaTures DescripTion
300MHz to 4GHz Active
Downconverting Mixer with
Wideband IF
The LTC
®
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.
The RF input is 50Ω matched from 1.4GHz to 3GHz, and
easily matched for higher or lower RF frequencies with
simple external matching. The LO input is 50Ω matched
from 1GHz to 4GHz, even when the IC is disabled. The LO
input is easily matched for higher or lower frequencies, as
low as 300MHz, with simple external matching. The low
capacitance differential IF output is usable up to 2.5GHz.
