4G/5G MIPI LNA and LNA bank

Low-noise amplifier MMICs for mobile cellular systems: 4G and 5G

anchor

Overview

Infineon LTE (4G) and 5G Mobile Industry Processor Interface (MIPI) LNA MMICs are designed to optimize the sensitivity of mobile cellular systems. These MMICs contain gain-switching, biasing, and matching circuitry, and thus allow easy implementation into the RF design. The Infineon portfolio includes a wide variety of solutions from single to quad LNAs in very small standard IC packages optimized for standard cellular frequency bands to address customer needs, including high-linearity LNAs with bypass enable 4 x 4 MIMO reception with high power transmit signals. Infineon 4G/5G LNAs are used in many reference designs of chipset vendors, but can also be found in customized solutions that aim to compensate losses from the antenna to the transceiver; in complex multi-band front-end implementations or long signal lines from distributed antennas or to improve overall system performance.

Key Features

  • Up to 6 GHz
  • Up to 21 dB gain
  • Up to 0.5 dB NF
  • Up to 4.3 mA

About

Infineon's extensive range of 4G/5G MIPI LNA solutions

Using MIPI LNAs provide many benefits:

  • Offers high integration capabilities, simplifying the overall system design and reducing complexity.
  • Designed to provide low Noise Figure (NF), resulting in improved receiver sensitivity and allowing cellular systems to detect and process weak signals more effectively.
  • Provides high linearity, which helps maintain signal integrity and prevent interference, while also improving the dynamic range of the receiver, ensuring reliable reception.
Low Noise Figure (NF), high-linearity, and low-power LNAs

LTE LNAs and 5G LNAs with high linearity are a great addition to smartphones and other applications with a moderate amount of signal interference. These LNAs guarantee that the signal maintains its quality no matter the circumstances. Lower NF results in better signal reception.?

Infineon¡¯s range of 4G/5G LNAs with low NF fit in all applications. Low power consumption is a very important feature for applications where power saving is a main requirement. All applications benefit greatly from low-power LNAs mainly due to their dependence on battery life.
