RF Receivers - MAX1473ETJ+T Application Field and Working Principle

MAX1473ETJ+T is a receiver and controller combo part designed to work with all of the common RF standards used within many consumer electronic products. It is an exceptional part with its ability to work with such a diverse range of operating frequencies and signal modulation types. The part is suitable for use in applications where a greater range of operating frequencies is specified, including, but not limited to, 315MHz, 433.92MHz, 868MHz, and 915MHz. In addition, it has the ability to work with many types of signal modulation including 2FSK, GFSK, MSK, and OOK in order to provide a flexible receiver solution. The MAX1473ETJ+T not only operates across a range of frequencies with a selection of modulation types, it also incorporates a Low-Power Readout mechanism to ensure that any transmitted data is quickly and accurately received without causing undue interference in other functions within the system. It also incorporates an On-Chip comparator to reduce noise and provide improved signal conditioning prior to data readout. The MAX1473ETJ+T has an in-built low power consumption and sleep mode that ensures the device remains powered down until a signal is received, significantly reducing the power usage of an entire connected system. This also enhances the overall design flexibility of the part, providing an optimised solution when interoperability and low power consumption are required. In addition, the MAX1473ETJ+T is available in a JEDEC SSOP20 package, which allows the part to be integrated into a mobile device or remote controller in a space saving manner. This ensures that the overall design processes remain cost effective and allows for the higher density integration compared to other similar solutions.When using the MAX1473ETJ+T receiver, the power supply and GND pins must be attached according to the datasheet, as incorrect attachment may adversely affect the performance of the receiver. The attached antenna must be tuned according to the operating frequency of the part, with the details of the tuning included in the product datasheet. The MAX1473ETJ+T receiver requires an additional "frequency stabilization" circuit to help optimize its gain. This is done by adjusting the frequency of the receiver for the specific operating frequency. This can be done by using PLL or an image rejection oscillator, both of which are supplied in the MAX1473ETJ+T data sheet. In terms of efficiency, the MAX1473ETJ+T has an impressive sensitivity of -114 dBm, and a high maximum data rate of 2Mbps. This allows the receiver to capture a wide range of signals with minimal power requirement. It also has a high conversion gain of 20 dB, allowing the signal to be received with confidence. Overall, the MAX1473ETJ+T is an ideal solution in RF receivers due to its high performance, low power consumption, and slim footprint. It includes a range of features that make it well suited to a variety of consumer applications, including remote control systems and low data rate communications. Its comprehensive datasheet provides in-depth information on the operating principles and setting up of the receiver, and its parts are readily available for purchase.
