RF Receivers: MAX2160EBG+TW Application Field and Working Principle

MAX2160EBG+TW is a high-performance, two-stage low-noise amplifier (LNA) from Maxim Integrated, designed for RF receivers in consumer mobile applications. It is designed for wide-band operation in the 800 MHz to 2.2 GHz frequency range, and supports a variety of wideband applications such as WCDMA, CDMA, GSM, WCS, WiMAX and LTE. It also supports the operation in the low- band PMR community, such as Tetra and various VHF & UHF standards.

Features of MAX2160EBG+TW

MAX2160EBG+TW offers several features, such as a wide gain range from +13dB to +30dB, a low noise figure of 2.0dB maximum, an adjustable gain, and a low-power consumption of 3.5mA typical. It also offers a low input and output return loss and an excellent input-referred 1dB compression point of +7.9dBm, making it suitable for applications where the signal strength of incoming signals needs to be boosted or matched.

Application Fields of MAX2160EBG+TW

MAX2160EBG+TW is suitable for all kinds of RF receivers. It is used in consumer mobile applications such as WCDMA, CDMA, GSM, WCS, WiMAX, LTE, Tetra, VHF, and UHF systems. It is also used in smart phones and other wireless devices, for both transmission and reception applications.

Working Principle of MAX2160EBG+TW

The main function of the MAX2160EBG+TW is to amplify the RF signal from the antenna, so that it can be further processed by the receiver. This is done through a two-stage low-noise amplifier (LNA).The MAX2160EBG+TW consists of two stages. The first stage is an amplifier with a gain of +14 dB, and the second stage is a variable gain amplifier (VGA) with a gain of +13 to +30 dB. The gain of the VGA is adjustable by an external voltage applied to its control pin. The gain of the MAX2160EBG+TW is also adjustable by changing the drain bias current, allowing the user to optimize the performance.The device has a very low noise figure, which is critical in RF applications. The noise figure indicates the overall noise contribution of a device, from the antenna channel up to the output. A lower noise figure usually corresponds with a higher signal-to-noise ratio (SNR), meaning that the device is better able to discriminate between noise and the desired signal. The MAX2160EBG+TW also has a low input return loss and a good input-referred 1dB compression point. Input return loss is an important parameter to ensure that the input signal is not distorted, and the 1dB compression point indicates the power level at which the device starts to compress the input signal. These two parameters together ensure that the amplifier is able to reproduce the incoming signal accurately and faithfully.Overall, the MAX2160EBG+TW is an ideal solution for RF receivers, providing excellent performance and low power consumption. It is widely used in consumer mobile applications such as WCDMA, CDMA, GSM, WCS, WiMAX, LTE and PMR. Its adjustable gain, low noise figure, low input return loss, and good input-referred 1dB compression point make it ideal for boosting and matching signals, so that they can be accurately and faithfully received.
