Product Overview

The LTC5591IUH#PBF is a dual-channel high dynamic range, high gain downconverting mixer, part of a family covering the 600MHz to 4.5GHz RF frequency range. It is optimized for 1.3GHz to 2.3GHz RF applications, with the LO frequency best performing within 1.4GHz to 2.1GHz. Typical applications include LTE or W-CDMA multichannel/diversity receivers.

Key Features

• High Conversion Gain: Typical 8.5dB at 1950MHz, enhancing signal strength effectively.
• Excellent Dynamic Range: IIP3 of 26.2dBm at 1950MHz, ensuring linearity in strong interference environments.
• Low Noise Figure: 9.9dB at 1950MHz (15.5dB under 5dBm blocking), maintaining signal purity.
• High Channel Isolation: >47dB channel-to-channel isolation, minimizing crosstalk between channels.
• Flexible Power Modes: Supports low current mode with <800mW total consumption and independent channel shutdown, adapting to varying power needs.

Technical Specifications

Typical Applications

• LTE/W-CDMA Diversity Receivers: In LTE/W-CDMA systems, LTC5591IUH#PBF efficiently processes 1.7GHz to 2.2GHz RF inputs with low-side LO, ensuring stable downconversion and improving signal quality in diversity reception.
• 3G/4G Wireless Infrastructure: Ideal for 3G/4G base station diversity receivers, its high dynamic range captures weak signals reliably in complex wireless environments.
• Remote Radio Units (RRUs): Compact size and flexible power modes fit RRU constraints, while high isolation ensures stable operation in remote locations.
• MIMO Multichannel Receivers: 47dB channel isolation reduces crosstalk in MIMO systems, enhancing multi-antenna communication capacity and reliability.
