MAX7044AKA-T

RF Transmitter Overview

The MAX7044AKA-T is a high-efficiency, crystal-based ASK transmitter operating in the 300MHz to 450MHz frequency range. It features an integrated phase-locked loop (PLL) and delivers +13dBm output power. The device supports data rates up to 100kbps and utilizes OOK/ASK modulation. Packaged in an 8-pin SOT-23, it is designed for low-power wireless applications requiring reliable transmission within the specified VHF/UHF bands.

RF Transmitter Feature Summary

• Integrates a crystal-referenced PLL for stable frequency generation
• Delivers high-efficiency RF transmission with +13dBm output power
• Supports ASK/OOK modulation schemes for simple data encoding

RF Transmitter Applications

• Wireless remote control systems
• Low-power sensor networks
• Telemetry data transmission

RF Transmitter Procurement Notes

Verify the suffix '+T' indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check for RoHS compliance markings on the datasheet documentation. Ensure the specific variant aligns with the required frequency band specifications for your design.

RF Transmitter Selection Notes

Select this component for designs requiring a compact solution with integrated frequency synthesis. The SOT-23 package suits space-constrained PCB layouts. Consider the 100kbps data rate limit when evaluating throughput requirements. The crystal-based architecture simplifies external oscillator needs compared to RC-based alternatives.

RF Transmitter Part Context

This part belongs to the MAX7044 family of VHF/UHF transmitters. It shares architectural similarities with other Maxim Integrated RF solutions but is distinct in its specific crystal-reference PLL implementation. The family focuses on cost-effective, high-efficiency transmission for industrial and consumer wireless markets.

RF Transmitter Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative ASK transmitters from the same manufacturer only if they match the 300-450MHz range and SOT-23-8 footprint. Verify pin compatibility and electrical parameters before substitution.
