MICRF113

In Production

The MICRF113 is a high-performance, easy-to-use, single-chip ASK Transmitter IC for remote wireless applications in the 300MHz to 450MHz frequency band. This transmitter IC is a true "data-in, antenna-out" monolithic device.

MICRF113 has three strong attributes: power delivery, operating voltage and operating temperature. In terms of power, the MICRF113 is capable of delivering +10dBm into a 50Ω 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 MICRF113 operates from 1.8V to 3.6V. Many transmitter ICs in the same frequency band stop operating below 2.0V. The MICRF113 will work with most batteries to the end of their useful limits. In terms of operating temperature, the MICRF113 operates from -40°C to +85°C.

The MICRF113 is easy to use. It requires a reference frequency (RF carrier frequency divided by 32 times) generated from a crystal with a few additional external parts to create a complete versatile transmitter.

The MICRF113 operates with Amplitude Shift Keying/On-Off Keyed (ASK/OOK) UHF receiver types from wide-band super-regenerative radios to narrow-band, high-performance super-heterodyne receivers. The MICRF113's maximum ASK bit rate is 20kbps (minimum pulse width of 50µs at ASK pin).

The MICRF113 transmitter solution is ideal for industrial and consumer applications where simplicity and form factor are important.
