Mic2290 48v Avalanche Photo Diode (apd) Application Circuit W/ 0603 Chip Inductor

The MICRF112 is a high-performance, user-friendly, single-chip ASK/FSK transmitter integrated circuit (IC) designed for remote wireless applications within the 300 to 450 MHz frequency band. This transmitter IC features a true data-in, antenna-out configuration. The MICRF112 excels in three key areas: power delivery, operating voltage, and operating temperature. In terms of power, the MICRF112 can deliver +10 dBm into a 50-ohm load, allowing compact transmitter designs, such as key fob transmitters, to operate close to the maximum limits of transmission regulations. Regarding operating voltage, the MICRF112 functions effectively from 3.6V down to 1.8V, whereas many competing transmitter ICs in the same frequency range cease operation below 2.0V. This capability enables the MICRF112 to utilize most battery types until they reach their end-of-life. The operating temperature range for the MICRF112 spans from -40°C to +125°C, making it suitable for demanding applications, such as tire pressure monitoring systems. By Micrel Semiconductor.

The MICRF112 transmitter IC is designed to facilitate robust wireless communication in various applications, particularly those requiring reliable operation in challenging environments. Its ability to deliver +10 dBm output power into a 50-ohm load is critical for ensuring effective transmission over extended distances, which is essential for remote control devices, sensor networks, and other wireless systems.

The voltage operating range of 1.8V to 3.6V is particularly advantageous, as it allows the device to function with a wide variety of power sources, including lithium-ion batteries and alkaline cells. This flexibility is beneficial in applications where battery life is crucial, as the MICRF112 can continue to operate efficiently as the battery voltage declines.

Additionally, the wide temperature range of -40°C to +125°C enhances the MICRF112's suitability for industrial and automotive applications, where devices are often subjected to extreme environmental conditions. This resilience ensures that the transmitter maintains performance reliability in situations such as tire pressure monitoring systems, where temperature fluctuations can be significant.

The integration of ASK/FSK modulation capabilities within a single chip simplifies the design process for engineers, reducing the need for external components and minimizing the overall footprint of the circuit. This integration not only helps in saving space but also enhances the reliability of the system by reducing the number of potential failure points.

Overall, the MICRF112 is a versatile and high-performance transmitter IC that meets the demands of modern wireless communication applications, providing engineers with a powerful tool for developing reliable and efficient wireless systems.The MICRF112 is a high performance, easy to use, single chip ASK / FSK Transmitter IC for remote Wireless applications in the 300 to 450MHz frequency band.
