Product overview
Imported RF Receiver MICRF112YMM, a high performance, easy to use, single-chip ASK / FSK Transmitter IC For remote wireless applications in the 300 to 450 MHz band. This transmitter IC is a true "data input, antenna out" iron plate piece of equipment.
Detailed description

The MICRF112 is high performance in three field areas: electric power transmission, operating voltage, and operating temperature. In terms of power, the MICRF112 is capable of delivering a 50Ω load of +10dBm. This power level enables small form factor transmitters (lossy antennas), such as maximum limit operational transmission regulations near portable information terminal transmitters. In terms of operating voltage, the MICRF112 operates from 3.6V to 1.8V. Many stop operating the transmitter IC 2.0V or less in the same frequency band. The MICRF112 can end with its useful limits for most batteries to work with. In terms of operating temperature, the MICRF112 operates over a temperature range of -40 ° C to + 125 ° C. This wide operating temperature range makes the MICRF112 an ideal candidate for demanding applications such as tire pressure monitoring systems. The MICRF112 is easy to use. One only needs a reference frequency (RF carrier frequency divided by 32 times) to create a complete multi-function transmitter from the crystal with several additional external parts. The MICRF112 with ASK / OOK (Amplitude Shift Operation Keying / On - Critical Control) from Wideband UHF Receive Type Super Regenerative Radio Narrow Band, High performance superheterodyne receiver. The MICRF 112 has a maximum ASK data rate of 50 kbps (Manchester Code). It operates as an FSK receiver. The chip is designed to support narrowband FSK (Frequency Shift Modulation) by switching external capacitors in parallel with the reference crystal. The maximum FSK data rate of the MICRF 112 is 10 kbps.
