LTC5591 - Dual 1.3GHz to 2.3GHz High Dynamic Range Downconverting Mixer

The LTC®5591 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 LTC5591 is optimized for 1.3GHz to 2.3GHz RF applications. The LO frequency must fall within the 1.4GHz to 2.1GHz range for optimum performance. A typical application is a LTE or W-CDMA multichannel or diversity receiver with a 1.7GHz to 2.2GHz RF input and low side LO.

The LTC5591’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.

Features Conversion Gain: 8.5dB at 1950MHz IIP3: 26.2dBm at 1950MHz Noise Figure: 9.9dB at 1950MHz 15.5dB NF Under 5dBm Blocking High Input P1dB 47dB Channel-to-Channel Isolation 1.25W Power Consumption at 3.3V Low Power Mode: <800mW Consumption Independent Channel Shutdown Control 50Ω Single-Ended RF and LO Inputs LO Input Matched In All Modes 0dBm LO Drive Level Small Package and Solution Size –40°C to 105°C Operation Typical Application
