The MICRF112YMU-TR is a type of RF Transmitter used in various electronic applications. This low-power and low-cost transmitter operates in the 315MHz ISM band and transmits data, commands, control signals, or digital messages up to 100m/165ft in free-space, depending on antenna type and implementation.

The main features and performance of this device include an extremely low power consumption of only 1.28mW while transmitting, a two-pin configuration with a 50Ω output impedance, minimal current drain in power saving modes, a range of selectable frequencies, and the ability to program custom frequencies. The open-loop gain of the device is a respectable 18dB with a VCC of 3V and a frequency tolerance of ±200kHz.

In addition to this, the MICRF112YMU-TR also features exceptional emission power which can reach up to +12 dBm with a VCC of 3.3V. Its wide transmission range is attributed to its 10dB typical gain, and its extremely low harmonic emissions are conformed to the ETSI 300-220 standard, furthermore ensuring high-quality transmissions.

The key components of the transmitter include a dielectric resonator oscillator (DRO) unit, RF power amplifier, and power control circuit. The DRO unit creates the signals for transmission in the ISM band via a dielectric resonator. These signals are then manipulated by the power control circuit to determine the RF current and output power, while the amplifier boosts these signals to the required transmission power.

The power control circuit also allows for direct input of modulation data, enabling the device to be operated with manual control rather than programmed. With the MCU-transmitter interface direct control system, the user-customizable periods of transmission and power can be set. This feature adds significant convenience, and the easy-to-program interface guarantees reliability and precision.

The MICRF112YMU-TR is widely used in remote-control projects, systems integration, identifications and security systems, as well as many different types of instrumentation. With its superior power, greatly increased frequencies, and outstanding dynamic range, the transmitter is perfect for a variety of low-power transmission needs.
