ADS58C23IPFP

RF Front End (LNA + PA) can be used in many disciplines, including wireless communication, satellite communication, multi-hop relay communication, and cognitive radio communication. There have been various advances in RF Front End (LNA + PA) over the years, but the ADS5823IPFP is one of the most recent and advanced products in this category. It is an ultra-low noise, low power, high linearity, and high gain amplifier with a unique pin-compatible interface. In this article, we will discuss the application field and the working principle of the ADS58C23IPFP.

Application Field

The ADS58C23IPFP is primarily used in networks and systems which require high linearity and low noise solutions in a low power package. This makes the device ideal for applications such as high speed Fourier Transform (FT) communication system, which involves fast Fourier transforms of the signal, transport special signal data processing and detection such as in deep space communication, or where a large number of channels need to be monitored in a short time span. Moreover, the device is also suitable for applications in broadcast, military, industrial, medical, and consumer electronics.

Working Principle

The ADS58C23IPFP consists of three sections: the Low Noise Amplifier (LNA), the Power Amplifier (PA), and the Coupling network. The Low Noise Amplifier (LNA) portion of the device utilizing a low noise active BiCMOS process has a typical noise figure (NF) of 0.50dB at 1GHz and a gain of 17dB. It can be configured to operate from DC to 3GHz. The LNA also provides an integral power-down feature which can be used for power saving. The Power Amplifier (PA) portion has high power handling capability and can provide up to +25dBm of linear output power, while drawing very low current of only 1.5mA. It also has a built-in thermal shutdown feature, so it can protect the device inside the amplifier from possible damage due to excessive thermal buildup. The Coupling Network is used to control the generated output power and creates impedance matching for the device when attached to the antenna.

In summary, the ADS58C23IPFP is a unique RF Front End (LNA + PA) solution which has been designed to provide ultra-low noise, low power, and high linearity performance in the network and systems. Its application field is in wireless communication, satellite communication, multi-hop relay communication, broadcast, military, industrial, medical, and consumer electronics. Its working principle is based on a unique pin-compatible interface which includes a Low Noise Amplifier (LNA), a Power Amplifier (PA), and a Coupling Network.
