QwikRadio™ UHF ASK Transmitter
Final
General Description
The MICRF103 is a single chip Transmitter IC for remote
wireless applications. The device employs Micrel’s latest
QwikRadio™ technology. This device is a true ”data-in,
antenna-out” monolithic device. All antenna tuning is accom-
plished automatically within the IC which eliminates manual
tuning, and reduces production costs. The result is a highly
reliable yet extremely low cost solution for high volume
wireless applications. Because the MICRF103 is a true
single-chip radio transmitter, it is easy to apply, minimizing
design and production costs, and improving time to market.
The MICRF103 uses a novel architecture where the external
antenna is tuned by the internal UHF synthesizer. This
transmitter is designed to comply worldwide UHF unlicensed
band international radio regulations. The IC is compatible
with virtually all ASK/OOK (Amplitude Shift Keying/On-Off
Keyed) UHF receiver types from wide-band super-regenera-
tive radios to narrow-band, high performance super-hetero-
dyne receivers. The transmitter is designed to work with
transmitter data rates up to 115k bits per second.
The automatic tuning in conjunction with an external resistor,
insures that the transmitter output power stays constant at
maximum regulatory transmit power limits for the life of the
battery.
When coupled with Micrel’s family of QwikRadio™ receivers,
the MICRF103 provides the lowest cost and most reliable
remote actuator and RF link system available.
