MICRF113YM6-TR: A 3V UHF ASK Transmitter Microchip

The MICRF113YM6-TR is a highly integrated, monolithic UHF ASK (Amplitude Shift Keying) transmitter designed for low-power wireless applications. Operating from a single 3V power supply, this microchip from Microchip Technology provides a compact and efficient solution for transmitting digital data over radio frequencies in the 300 MHz to 450 MHz band. Its combination of low voltage operation, minimal external components, and simple interfacing makes it a preferred choice for designers of remote keyless entry systems, tire pressure monitoring sensors, home automation devices, and various short-range telemetry applications.

A key advantage of the MICRF113YM6-TR is its high level of integration. The chip incorporates a crystal oscillator, phase-locked loop (PLL), and a power amplifier on a single die. This architecture drastically reduces the bill of materials and required board space. Designers only need to connect a low-cost reference crystal, a few passive components, a power source, and an antenna to create a fully functional transmitter. This simplicity accelerates development time and lowers overall system cost.

The device is engineered for exceptional power efficiency, a critical parameter for battery-operated devices where longevity is paramount. It features a low operating current and supports a shutdown mode that reduces current consumption to mere microamps when the transmitter is inactive. This allows end products to conserve power and achieve extended battery life, often lasting for several years on a single cell.

Furthermore, the MICRF113YM6-TR offers reliable performance. Its PLL-based frequency synthesizer ensures stable and accurate carrier frequency generation, which is immune to environmental factors like temperature drift that can affect simpler transmitter designs. Data input is straightforward, accepting serial digital information for direct ASK modulation, making it easy to interface with common microcontrollers.

ICGOOODFIND: The MICRF113YM6-TR stands out as an optimal solution for developers seeking a reliable, low-power, and cost-effective UHF transmitter. Its high integration minimizes design complexity, while its robust performance ensures dependable wireless communication for a wide array of consumer and industrial products.
