MICROCHIP  MICRF112YMM  芯片, 发送器, ASK/FSK, UHF, MSOP10

The is a QwikRadio® UHF ASK/FSK Transmitter for remote wireless applications in the 300 to 450MHz frequency band. This transmitter IC is a true data-in, antenna-out monolithic device. The transmitter is high performance in three areas: power delivery, operating voltage and operating temperature. In terms of power, the transmitter is capable of delivering +10dBm into a 50R load. This power level enables a small form factor transmitter lossy antenna such as a key fob transmitter to operate near the maximum limit of transmission regulations. In terms of operating voltage, the transmitter operates from 3.6 to 1.8V. Many transmitter ICs in the same frequency band stop operating below 2V. It will work with most batteries to the end of their useful limits. This wide operating temperature range makes transmitter an ideal candidate for the demanding applications such as a tire pressure monitoring system.
