An RF amplifier is an electronic device or circuit that increases the strength of a signal. The AWB7225P8 is an RF amplifier that amplifies signals in the 2.125-2.6GHz frequency range. It is a three-stage amplifier that offers wide instantaneous bandwidth, high gain and low noise figure. This makes it ideal for applications such as point-to-point radio links, radar systems and satellite receivers.

AWB7225P8 Application Field

The AWB7225P8 is designed to operate in various applications including base station receivers, point-to-point radios, radar systems, and satellite receivers. It can amplify very small signals at frequencies between 2.125 - 2.6GHz. Additionally, the AWB7225P8 can be used in point to point radio links, enabling users to communicate over a distance.

In base station receivers, the AWB7225P8 can be used to amplify very weak signals, allowing for a clearer and more reliable signal. For space communications, the AWB7225P8 can be used to amplify signals from satellites, allowing them to be received clearly.

AWB7225P8 Working Principle

The AWB7225P8 can easily be built into radio systems due to its low-noise amplifier circuit and single-supply operation. This amplifier is built with three stages. The first stage is called the input stage, which consists of an active source-follower transistor. The second stage is a common source amplifier, which provides gain and bandwidth. The final stage is the output stage, which consists of a pair of cascode transistors to provide the output signal in a broadband frequency range.

The AWB7225P8 uses GaAs MESFETs, which have a high frequency performance, wide instantaneous bandwidth, and good Figure of Merit. This combination of active devices allows the amplifier to achieve a gain of 20dB and a 3dB bandwidthof 400MHz. Additionally, the amplifier can provide low noise figure. The noise can be decreased in the -10dB range by changing the source resistance from 10Ω to 30Ω. This allows the amplifier to receive very weak signals.

Conclusion

The AWB7225P8 is a three-stage amplifier designed for applications in the 2.125-2.6GHz frequency range. The amplifier provides higher gain and better noise figure than conventional amplifiers with excellent bandwidth and stability. This makes it suitable for point-to-point radio links, base station receivers, radar systems, and satellite receivers.
