LTC5590 - Dual 600MHz to 1.7GHz High Dynamic Range Downconverting Mixer

The LTC®5590 is part of a family of dual-channel high dynamic range, high gain downconverting mixers covering the 600MHz to 4.5GHz RF frequency range. The LTC5590 is optimized for 600MHz to 1.7GHz RF applications. The LO frequency must fall within the 700MHz to 1.5GHz range for optimum performance. A typical application is a LTE or GSM receiver with a 700MHz to 915MHz RF input and high side LO.

The LTC5590’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. A low current mode is provided for additional power savings and each of the mixer channels has independent shutdown control.
