General Description

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.
