Introducing the MAX1472AKA - Maxim Integrated's Low-Power, 300-450MHz ASK Transmitter

The MAX1472AKA from Maxim Integrated is a highly efficient, low-power amplitude-shift keying (ASK) transmitter designed for the 300MHz to 450MHz frequency bands. This compact and versatile component is ideal for short-range wireless communication applications, including remote keyless entry (RKE), garage door openers, and wireless security systems.

The device operates from a single 2.1V to 3.6V supply, making it suitable for battery-powered applications. Its low current consumption ensures extended battery life, which is crucial for maintenance-sensitive devices. The MAX1472AKA can transmit data rates up to 100kbps, allowing for quick and reliable transmission of information.

One of the standout features of the MAX1472AKA is its integrated crystal oscillator, which eliminates the need for an external resonator. This on-chip oscillator requires only a low-cost crystal to function, simplifying the design and reducing the overall bill of materials. Additionally, the transmitter's frequency can be programmed with a single external resistor, giving designers flexibility and precision in setting the operating frequency.

The MAX1472AKA also boasts excellent frequency stability and minimal drift over temperature and supply voltage variations, ensuring reliable performance in a wide range of environmental conditions. Its output power is also programmable, allowing for compliance with various global regulatory standards.

For designers looking to minimize external components and maintain a compact form factor, the MAX1472AKA comes in a small 8-pin SOT23 package. Its small size and low external component count make it an excellent choice for space-constrained applications.

Overall, the MAX1472AKA is a robust, easy-to-use ASK transmitter that combines high performance with low power consumption. Its integration, programmability, and compliance with regulatory standards make it an ideal choice for developers looking to create efficient and reliable wireless communication solutions.
