The LMH6401IRMZR from Texas Instruments is a high-performance, digitally controlled variable gain amplifier (DVGA) designed to meet the rigorous demands of modern communication systems. This amplifier is part of TI's PowerWise® family, offering outstanding dynamic performance while maintaining efficiency across a wide range of operating conditions.

Key Features

• Frequency Range: The device operates over a broad frequency range from DC to 10 GHz, making it suitable for a wide variety of RF and IF applications.
• Gain Control: With a digital gain control range of 31.5 dB in 0.5 dB step increments, the LMH6401IRMZR allows for precise gain setting, which is essential for applications requiring accurate signal amplitude adjustments.
• High Linearity: Exhibiting an OIP3 of 43 dBm at 200 MHz, this amplifier maintains a high degree of linearity, ensuring minimal signal distortion even at high output power levels.
• Low Noise Figure: The low noise figure of 4.5 dB at maximum gain optimizes system sensitivity and dynamic range.
• Power Efficiency: The device operates with a single 5V supply and features a power-down capability, which reduces power consumption when the amplifier is not in active use.

Applications

• Wireless Infrastructure (e.g., 3G, 4G, and 5G base stations)
• Test and Measurement Equipment
• Military and Aerospace Systems
• Broadband Fixed Line Applications
• High-Speed Data Acquisition Systems
