Broadcom's MGA series Low noise amplifiers (LNAs) are high-performance, low-noise, and low-power consumption amplifiers designed for a wide range of wireless communication applications. They operate in the frequency range of 0.05 GHz to 6 GHz, providing a gain of up to 40 dB with a noise figure as low as 0.6 dB. These LNAs offer high linearity and can be operated with a single positive supply voltage. They are commonly used in cellular infrastructure, wireless LAN, small cell and distributed antenna systems, public safety radios, ISM band radios, and satellite communication systems.
Features
The main features of MGA series Low noise amplifiers may be summarized as follows:
1. Low Noise Figure: These LNAs have a low noise figure, which means that they generate very little noise when amplifying weak signals. This is particularly important in applications where signals are weak, such as in wireless communications or GPS systems.
2. High Gain: The MGA series LNAs have a high gain, which means that they can amplify weak signals to a higher level. This allows for better signal reception and transmission in communication systems.
3. Wide Bandwidth: These LNAs have a wide bandwidth, which means that they can operate over a range of frequencies. This makes them suitable for use in a variety of applications, including wireless communications, test and measurement equipment, and radar systems.
4. Low Power Consumption: The MGA series LNAs have low power consumption, which is important for battery-powered devices. This helps to extend the battery life of devices such as wireless sensors and mobile devices.
5. Small Size: These LNAs are available in small surface mount packages, making them suitable for use in compact devices where space is limited.
6. Integrated Bias Circuitry: Some versions of the MGA series LNAs include integrated bias circuitry, which simplifies the design process and reduces the number of external components required.

The MGA series amplifiers are commonly used in wireless communication systems, including cellular and satellite communication, WiFi, Bluetooth, and other wireless networking protocols. They are used to amplify the signals and improve the signal-to-noise ratio, making them essential for reliable communication.MGA series amplifiers are used in GPS (Global Positioning System) receivers to amplify the signals received from GPS satellites. These signals are very weak and need to be amplified before they can be used for navigation.
