DESCRIPTION
Demonstration Circuit 1710A-D is a dual 2.3GHz to
4.5GHz high dynamic range downconverting mixer
featuring the LTC
®
5593. The LTC5593 is part of a
family of dual-channel high dynamic range, high
gain downconverting mixers covering the 600MHz
to 4.5GHz frequency range. The Demo Circuit
1710A-D and the LTC5593 are optimized for
2.3GHz to 4.5GHz RF applications. The LO fre-
quency must fall within the 2.1GHz to 4.2GHz
range for optimum performance. A typical appli-
cation is a LTE or WiMAX multichannel or diversity
receiver with a 2.3GHz to 2.7GHz RF input.
The LTC5593 is designed for 3.3V operation, how-
ever the IF amplifiers can be powered by 5V for the
highest P1dB. A low current mode is provided for
power savings, and each of the mixer channels
has independent shutdown control.
The LTC5593’s high conversion gain and high dy-
namic range enable the use of lossy IF filters in
high-selective receiver designs, while minimizing
the total solution cost, board space and system-
level variation.
