Detailed description

The MICRF113 is a high performance, easy to use single-chip ASK transmitter IC for remote wireless applications in the mine's 300MHz to 450MHz band.This transmitter IC is a real "data input, antenna out" iron plate piece device.MICRF113 has three strong attributes: power transfer, operating voltage and operating temperature. The MICRF113 in the terms ofpower is capable of delivering +10dBminto50Ω load.

This power level allows small size transmitters (lossy antennas), such as the key fobtransmitter to operate close to the maximum limit of transmission. In terms of operating voltage, theMICRF113 operates from 1.8V to 3.6V.Many transmitter ICs in the same band stop operating below2.0V. The MICRF113 can work with most batteries and comes with a final limit of its own useful limitations.

In terms of operatingtemperature, MICRF113 operates from -40°CTO + 85°C. The MICRF113 is easy to use.

It needs to have some additional externalparts from the crystal to generate the referencefrequency (RF carrier frequency from 32 sub-fractions) to create a complete multi-function transmitter. The MICRF113 with operational amplitude shift keying / on-off keying (ASK / OOK) UHF Received from type wide-bandsuper-regenerativeradiostonarrow-band,
