MICRF102 pdf datasheet (QwikRa

The MICRF102 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, antennaout”
monolithic device. All antenna tuning is accomplished
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 MICRF102 is a true single-chip
radio transmitter, it is easy to apply, minimizing design and
production costs, and improving time to market.
The MICRF102 uses a novel architecture where the external
loop antenna is tuned to the internal output stage. This transmitter
is designed to comply with worldwide UHF unlicensed
band intentional radiator regulations. The IC is compatible with
virtually all ASK/OOK (Amplitude Shift Keying/On-Off Keyed)
UHF receiver types from wide-band super-regenerative radios
to narrow-band, high performance super-heterodyne receivers.
The transmitter is designed to work with transmitter data
rates from 100 to 20k bits per second.
The automatic tuning, in conjunction with the external resistor,
ensures that the transmitter output power stays constant for
the life of the battery.
When used with Micrel’s family of QwikRadio™ receivers,
the MICRF102 provides the lowest cost and most reliable
remote actuator and RF link system available.
