I. 4G/5G MIPI Low-Noise Amplifiers

4G/5G MIPI low-noise amplifiers are specialised RF amplifiers developed by Infineon for cellular mobile communication terminals. Unlike traditional GPIO-controlled LNAs, they feature a standardised MIPI control interface, enabling digital and precise mode control. They are perfectly suited to the communication requirements of 4G LTE all-network compatibility and mainstream 5G Sub-6GHz frequency bands, making them core RF components for smartphones, 5G modules and industrial cellular terminals.

1. Key Technical Features

This series of LNAs utilises a high-performance SiGe semiconductor process, combining an ultra-low noise figure with high gain to effectively compensate for losses in the RF front-end chain and significantly enhance the terminal’s reception sensitivity. The products support multiple operating modes, including multi-step gain adjustment, bypass mode and power-saving mode. Operating modes can be rapidly switched via the MIPI bus to adapt to complex and variable cellular signal environments, balancing communication performance with device battery life. They also feature excellent linearity, effectively suppressing multi-band signal interference to ensure 5G’s high-speed, low-latency transmission characteristics, whilst complying with 3GPP standardised frequency band specifications.

2. Mainstream Products and Key Parameters

Infineon’s 4G/5G MIPI LNA product portfolio covers the full spectrum of cellular networks, with its core best-selling products offering industry-leading performance parameters:

- BGM787U50: Features an integrated 7-channel LNA array with output cross-switching capability. Operating frequency range covers 600 MHz to 2,700 MHz, supporting the full 4G spectrum and 5G low-frequency bands. With a package size of just 2.8 × 2.8 mm², its ultra-high integration effectively reduces PCB space requirements in end devices, making it suitable for multi-band, all-network-compatible terminal equipment.

- BGA10H1MN9: Focuses on mainstream mid-bands such as 5G n41 (2.3 GHz–2.7 GHz), with a power gain of up to 19.7 dB, an ultra-low noise figure as low as 0.8 dB, and an operating current of just 6.0 mA. Utilising a MIPI interface to enable precise control of gain and bias modes, it significantly enhances the system’s dynamic range.

- BGA9C1MN9: Designed for the 5G high-frequency band (4.4 GHz–5.0 GHz), with a maximum gain of 19.0 dB and a noise figure of 0.9 dB. It supports stepwise gain adjustment, enabling dynamic optimisation of linearity and noise performance based on signal strength, making it suitable for 5G high-speed broadband transmission scenarios.

- BGA9U1MN9: Covers the 5 GHz–7.2 GHz ultra-high-frequency band, with a gain of 19.4 dB and a figure of noise of 1.2 dB. It features a wide supply voltage range (1.1 V–2.0 V) and is suitable for 5G ultra-wideband communication scenarios.

3. Core Application Scenarios

Primarily used in devices such as smartphones, tablets, 5G industrial modules, in-vehicle 4G/5G communication terminals and IoT cellular gateways, these solutions address the issues of high noise levels, inflexible control and poor multi-band compatibility found in traditional RF front-ends, ensuring stable, high-speed communication for terminals in weak-signal and complex electromagnetic environments.

II. GNSS Low-Noise Amplifiers

GNSS low-noise amplifiers are RF amplification devices developed by Infineon specifically for satellite positioning systems. Designed for global satellite navigation systems such as GPS, BeiDou, GLONASS and GALILEO, their core objective is to optimise satellite signal reception sensitivity to the utmost, addressing industry pain points such as weak signal penetration and susceptibility to interference. They are essential standard components for high-precision positioning terminals.

1. Key Technical Features

The core advantages of the GNSS LNA lie in its exceptionally low noise, high gain and high immunity to interference. Compared to general-purpose LNAs, this product series is optimised for narrowband satellite positioning signals, achieving industry-leading noise figures that maximise the recovery of faint satellite signals. At the same time, its high-gain characteristics effectively compensate for signal loss in the antenna and RF front-end, significantly improving satellite acquisition speed and positioning accuracy. The products incorporate electrostatic discharge (ESD) protection circuits and offer strong resistance to electromagnetic interference, making them suitable for complex operating environments such as in-vehicle, outdoor and industrial settings. Furthermore, their extremely low power consumption meets the long battery life requirements of portable positioning devices.

2. Key Product Advantages

Infineon’s GNSS LNAs have all passed rigorous testing for compatibility with positioning scenarios. They support the reception of signals from multiple satellite systems and can be directly integrated with mainstream positioning chip solutions without the need for additional matching circuits. The devices utilise a miniaturised package, making them suitable for slim and lightweight terminal designs. They also comply with the RoHS lead-free environmental standard, offering high reliability and a long service life to meet the requirements for long-term, stable operation in automotive and industrial-grade equipment.

3. Key Application Scenarios

Widely used in in-vehicle navigation systems, high-precision positioning modules, drone positioning systems, smart wearable positioning devices, industrial IoT positioning terminals, surveying and mapping instruments, and all other devices requiring satellite positioning, these components effectively enhance positioning stability and accuracy in scenarios such as tunnels, areas obstructed by high-rise buildings, and indoor environments with weak signals.

III. Multifunctional Low-Noise Amplifiers

Infineon’s multifunctional low-noise amplifiers are highly versatile and flexible broadband RF amplification devices that overcome the frequency limitations of specialised LNAs. Covering multi-band wireless communication scenarios, they balance cost-effectiveness with versatility, whilst prioritising multi-scenario adaptability, low power consumption and miniaturisation, making them the preferred solution for short-range IoT communication and general-purpose RF equipment.

This series of LNAs features a broadband design with an operating frequency of up to 6 GHz, covering mainstream IoT and short-range communication bands. It delivers balanced and outstanding core performance, with a maximum gain of 22 dB and an ultra-low noise figure as low as 0.6 dB. Furthermore, it offers extremely low standby and operating power consumption, with a typical operating current of just 4.3 mA. The products support flexible circuit adaptation solutions, allowing seamless integration into various customised RF systems. They are compatible with GPIO general-purpose control interfaces, and their simple circuit design eliminates the need for complex debugging, significantly reducing overall R&D costs and development cycles. The series comprises two main sub-categories: SiGe LNAs and broadband LNAs, allowing flexible selection based on bandwidth and gain requirements.

2. Key Product Highlights

The multi-functional LNA series is not restricted by demanding application scenarios and offers exceptional versatility, combining high performance with excellent adaptability: on the one hand, it delivers outstanding noise performance to meet the signal amplification requirements of mid- to high-end RF equipment; on the other hand, its extremely low power consumption makes it suitable for battery-powered portable devices. The miniaturised packaging design is ideal for lightweight terminals, whilst its excellent temperature stability ensures minimal performance degradation in both high and low-temperature environments, thereby enhancing device reliability.
