LTC5542
1.6GHz to 2.7GHz
High Dynamic Range
Downconverting Mixer
DESCRIPTION
The LTC®5542 is part of a family of high dynamic range passive
downconverting mixers covering the 700MHz to 4GHz
frequency range. The LTC5542 is optimized for 1.6GHz to
2.7GHz RF applications. The LO frequency must fall within
the 1.7GHz to 2.5GHz range for optimum performance. A
typical application is a LTE or WiMAX receiver with a 2.3GHz
to 2.7GHz RF input and low-side LO.
The LTC5542 is designed for 3.3V operation, however; the
IF amplifier can be powered by 5V for the highest P1dB.
An integrated SPDT LO switch with fast switching accepts
two active LO signals, while providing high isolation.
The LTC5542’s high conversion gain and high dynamic
range enable the use of lossy IF filters in high-selectivity
receiver designs, while minimizing the total solution cost,
board space and system-level variation.
