LTC5569
300MHz to 4GHz
3.3V Dual Active
Downconverting Mixer
FEATURES DESCRIPTION n n n n n n n n n n The LTCВ®5569 dual active downconverting mixer is optimized 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 circuit with enable pin. The symmetry of the IC assures that a phase and amplitude coherent LO is applied
to each mixer. High IIP3: 26.8dBm at 1950MHz
2dB Conversion Gain
Low Noise Figure: 11.7dB at 1950MHz
17dB NF Under 5dBm Blocking
44dB Channel Isolation
Low Power: 3.3V/600mW Total
Very Small Solution Size
Enable Pins for Each Mixer
Wide IF Frequency Range
LO Input 50О© Matched in All Modes
–40°C to 105°C Operation
16-Lead (4mm Г— 4mm) QFN package The RF inputs are 50О© matched from 1.4GHz to 3.3GHz,
and easily matched for higher or lower RF frequencies with
simple external matching. The LO input is 50О© matched
from 1GHz to 3.5GHz, even when one or both mixers are …
