Maxim Integrated MAX1472AKA+T Low-Power, 300-450MHz ASK Transmitter

The MAX1472AKA+T from Maxim Integrated is a highly integrated, low-power amplitude-shift keying (ASK) transmitter designed for the 300MHz to 450MHz frequency bands. This compact and efficient transmitter is a perfect choice for various wireless applications, including remote keyless entry (RKE), garage door openers, and home automation networks.

With its advanced design, the MAX1472AKA+T offers a simple and cost-effective RF transmission solution. It operates from a single 2.1V to 3.6V supply, making it suitable for battery-powered devices. The transmitter is capable of delivering output power up to +10dBm, ensuring robust signal transmission over a significant range.

The device features an adjustable output power level, which can be set via an external resistor. This flexibility allows designers to optimize the power consumption and range for their specific application needs. Additionally, the MAX1472AKA+T includes an onboard crystal oscillator circuit, which only requires an external crystal to set the operating frequency, simplifying the design and reducing external component count.

The MAX1472AKA+T is designed with ease of use in mind. It requires minimal external components, thanks to its integrated PLL and VCO, which saves board space and reduces system complexity. The device also provides a shutdown mode, which reduces the current consumption to less than 1µA, further extending battery life in portable applications.

Available in a compact 8-pin SOT23 package, the MAX1472AKA+T is designed to meet the demands of space-constrained applications. Its small footprint and low profile make it an ideal choice for integration into compact devices without sacrificing performance or functionality.

With its combination of low power consumption, high integration, and ease of use, the Maxim Integrated MAX1472AKA+T ASK transmitter is a versatile and reliable solution for designers looking to add wireless communication capabilities to their products.
