Maxim Integrated MAX7058ATG+T Crystal-Based Phase-Locked Loop (PLL) VHF/UHF Transmitter

The MAX7058ATG+T from Maxim Integrated is a versatile and high-performance crystal-based phase-locked loop (PLL) VHF/UHF transmitter designed for a wide range of wireless applications. This advanced transmitter IC is capable of generating frequency-modulated (FM) signals in the 300MHz to 450MHz range, making it an ideal choice for consumer electronics, remote controls, security systems, and telemetry applications that require reliable wireless communication.

Encased in a compact TQFN-24 package, the MAX7058ATG+T integrates a PLL VCO, a programmable divider, a buffer amplifier, and a power amplifier, streamlining the design process and reducing the external component count. The device supports frequency modulation with FSK (Frequency Shift Keying) and ASK (Amplitude Shift Keying) schemes, offering flexibility in modulation for various use cases.

One of the key features of the MAX7058ATG+T is its programmable frequency control that allows users to set the operating frequency with precision using an external crystal and the integrated programmable dividers. The transmitter's output power can be adjusted up to +13dBm, ensuring sufficient signal strength for the intended application while adhering to regulatory limits.

The MAX7058ATG+T also boasts low power consumption, with a supply voltage range of 2.1V to 3.6V, making it suitable for battery-powered devices. Its power-saving features include a shutdown mode that reduces the current consumption to a mere 0.1µA, further extending battery life in portable applications.

For designers concerned with regulatory compliance, the MAX7058ATG+T simplifies adherence to FCC Part 15 and similar international standards. Its high level of integration and ease of use make it a preferred choice for rapid development and deployment of wireless solutions.

With its robust feature set and high degree of integration, the Maxim Integrated MAX7058ATG+T is an excellent transmitter solution for designers looking to create efficient, high-performance wireless communication systems.
