The MICRF114 is a simple, low-cost OOK transmitter with programmable output power.  It is primarily intended for command and control applications (for example, Remote Keyless Entry (RKE) and Garage Door Opener (GDO) systems, etc.).  The transmitter is synthesizer based for high-frequency accuracy.  It operates on a single frequency which is determined by the frequency of the crystal connected to the built-in reference oscillator.  This frequency can be selected from a wide range.  The more popular transmit frequencies require readily available crystal frequencies (for example, a 13.56 MHz crystal for a 433.92 MHz transmit frequency). The RF performance of the transmitter is compliant with FCC and IC regulations, and with some Japanese standards.  European (ETSI) requirements can be met at low radiated power.

The MICRF114 is optimized for battery-powered applications that feature low current consumption and can operate over a wide supply voltage range.  Internal circuits sensitive to supply voltage variations run from the on-chip Low Dropout (LDO) regulator.  In order to reduce pin count and system Bill of Materials (BOM), the LDO regulator does not need an external capacitor for stability, and the single-pin reference oscillator has a programmable, integrated crystal load capacitor.  The single-ended RF output allows easy matching to monopole antennas with a minimal number of external components.
