High Dynamic Range
Downconverting Mixer
The LT C
®
5544 is part of a family of high dynamic range, high
gain passive downconverting mixers covering the 600MHz
to 6GHz frequency range. The LTC5544 is optimized for
4GHz to 6GHz RF applications. The LO frequency must
fall within the 4.2GHz to 5.8GHz range for optimum
performance. A typical application is a WiMAX receiver
with a 5.15GHz to 5.35GHz RF input and low side LO.
The LTC5544 is designed for 3.3V operation, however; the
IF amplifier can be powered with 5V for the higher P1dB.
The LTC5544’s high level of integration minimizes the total
solution cost, board space and system-level variation,
while providing the highest dynamic range for demanding
receiver applications.
