MAX262AEWG+T Application Field and Working Principle
The MAX262AEWG+T is an integrated, ultra low-power, dual low-pass active filter. It is designed for use with narrowband radio frequency (RF) receivers and transmitters. It is primarily used in wireless communication applications and is also suitable for applications in medical ultrasound and industrial process control. The MAX262AEWG+T combines dual low-pass active filters with integrated signal processing and linearization. It is an ideal solution for applications that require precise signal processing, low power consumption and good linearity.
MAX262AEWG+T Application Fields
The MAX262AEWG+T is designed to meet the needs of a variety of applications including:
- Wireless and portable communications, such as cellular phones, radio transceivers, and Bluetooth-enabled devices.
- RF tuners and receivers used in satellite and other radio reception applications.
- Industrial process control and medical ultrasound imaging.
The MAX262AEWG+T can be used in a wide range of operating parameters, from 0.5 dB to 2 dB of passband noise rejection. It handles input frequencies from 1 MHz to 3 GHz with maximum power consumption of only 50 mW.
MAX262AEWG+T Working Principle
The MAX262AEWG+T has two low-pass active filters. The first filter is a one-pole RC low-pass filter. The reactances of each pole are independently adjustable. This allows the filter to have a low-noise response and wideband frequency response. The second filter is a two-pole Sallen-Key low-pass filter. The poles of this filter are adjustable, as well. Together, these two filters provide precise signal processing with very low-power consumption.
In order to achieve maximized signal-to-noise ratio (SNR), the MAX262AEWG+T contains a linearizer, which adjusts the amplitude response of the filter. The linearizer is a circuit that adds automatic gain control (AGC) to the filter. This reduces saturation and distortion caused by signal spikes and other unwanted signals. The MAX262AEWG+T is able to achieve SNRs of better than 98 dB.
The MAX262AEWG+T provides very good performance in terms of harmonic distortion and spurious signal suppression. The device has a noise figure of less than 6 dB. In addition, the device has temperature compensation, which ensures that the signal is accurately filtered over a wide temperature range.
Conclusion
The MAX262AEWG+T is an integrated, ultra low-power, dual low-pass active filter for use with narrowband radio frequency (RF) receivers and transmitters. It has low-noise and wideband frequency response and is able to achieve signal-to-noise ratios of better than 98 dB. It delivers temperature compensation, as well as harmonic distortion and spurious signal suppression. It is a suitable solution for applications that require precise signal processing, low power consumption and good linearity.
