UHF ASK/FSK Transmitter
General Description
The MICRF112 is a high performance, easy to use, single
chip ASK / FSK Transmitter IC for remote wireless
applications in the 300 to 450MHz frequency band. This
transmitter IC is a true “data-in, antenna-out” monolithic
device.
MICRF112 is high performance in three areas: power
delivery, operating voltage, and operating temperature. In
terms of power, the MICRF112 is capable of delivering +10
dBm into a 50
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 MICRF112 operates from 3.6V to 1.8V. Many
transmitter ICs in the same frequency band stop operating
below 2.0V. The MICRF112 will work with most batteries
to the end of their useful limits. In terms of operating
temperature, the MICRF112 operates from -40°C to
+125°C. This wide operating temperature range makes
MICRF112 an ideal candidate for the demanding
applications such as a tire pressure monitoring system.
The MICRF112 is easy to use. One only needs 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 MICRF112 operates with ASK/OOK (Amplitude Shift
Keying/On-Off Keyed) UHF receiver types from wide-band
super-regenerative
radios
performance
super-heterodyne
MICRF112’s maximum ASK data rate is 50kbps
(Manchester Encoding). It operates with FSK receivers as
well. The chip is designed to support narrow band FSK
(Frequency Shift Modulation) by switching an external
capacitor in parallel with the reference crystal. The
MICRF112’s maximum FSK data rate is 10kbps.
