TYPICAL APPLICATION
FEATURES DESCRIPTION
300MHz to 4GHz
3.3V Dual Active
Downconverting Mixer
The LT C
®
5569 dual active downconverting mixer is opti-
mized for diversity and MIMO receiver applications that
require low power and small size. Each mixer includes an
independent LO buffer amplifier, active mixer core, and
bias cir
cuit with enable pin. The symmetry of the IC as
-
sures that a phase and amplitude coherent LO is applied
to each mixer.
The
RF inputs are 50Ω matched from 1.4GHz to 3.3GHz,
and easily matched for higher or lower RF frequencies with
simple external matching. The LO input is 50Ω matched
from 1GHz to 3.5GHz, even when one or both mixers are
disabled. The LO input is easily matched for higher or
lower frequencies, as low as 350MHz, with simple external
matching. The low capacitance differential IF outputs are
usable up to 1.6GHz.
