1.8V, QwikRadio UHF ASK Transmitter
Final Information
General Description
The MICRF104 is a low voltage Transmitter IC for remote
wireless applications. The device employs Micrel’s latest
QwikRadio technology. This device is a true “data-in,
antenna-out” 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. The MICRF104 incorporates a DC/DC con-
verter to boost the input voltage up to 5V for the RF portion of
the IC. This feature enables the MICRF104 to operate off
supply voltages as low as 1.8V and transmit at power in
excess of –2dBm.
The MICRF104 uses a novel architecture where the external
loop antenna is tuned to the internal UHF synthesizer. This
transmitter is designed to comply 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-regenera-
tive radios to narrow-band, high performance super-hetero-
dyne 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,
insures that the transmitter output power stays constant for
the life of the battery.
When coupled with Micrel’s family of QwikRadio receivers,
the MICRF104 provides the lowest cost and most reliable
remote actuator and RF link system available.
