RF Amplifiers

MMA20312BT1 is the first amplifier module designed specifically for radio frequency (RF) applications, It employs advanced wideband amplifier technologies to provide high performance operational characteristics. It is designed for use in a number of different applications that require a compact and reliable amplifier solution.

Application Field

The MMA20312BT1 is suitable for a variety of RF applications, including mobile and base station amplifiers, antenna matrices, active mixers, and telecommunications infrastructure. It can also be used as a power amplifier in some wireless applications. The amplifier has a high linearity, excellent frequency response, and excellent noise figure, making it ideal for use in demanding applications.

Working Principle

The MMA20312BT1 is a broadband amplifier that utilises a combination of linear and non-linear techniques in order to achieve the desired performance. Linear systems use an input/output relationship that is typically linear over a range of frequencies. Non-linear systems employ techniques such as distortion control and harmonic rejection to improve the output power of the amplifier.

The MMA20312BT1 combines both linear and non-linear techniques. The linear system is used to ensure that the amplifier operates in a linear and efficient manner. Non-linear techniques are used to improve the efficiency and linearity of the amplifier. These include pre-driver linearisation, peak-clipping linearisation, and post-driver linearisation. All these techniques ensure that the amplifier is able to deliver high output power, high linearity, and low distortion.

The MMA20312BT1 also employs a variety of frequency dependent circuits in order to maximise the efficiency of the amplifier. These include a low noise pre-driver amplifier, a bandpass filter to reject out of band signals, and a low noise post-driver amplifier.

The MMA20312BT1 is an ideal choice for a variety of RF applications due to its high performance characteristics and frequency dependant linearisation. Its low noise pre-driver amplifier, bandpass filter, and low noise post-driver amplifier combine to provide a comprehensive linear and non-linear amplifier solution.
