QwikRadio Sweep-Mode Receiver
General Description
The MICRF008 QwikRadio UHF receiver is a single-chip
OOK (on-off keyed) receiver IC designed for remote wireless
applications. This device is a true single-chip, “antenna-in,
data-out” device, and it is easy to implement. MICRF008
receiver requires very few peripheral passive components.
All tunings, RF and IF, are accomplished within the IC. Ease
of use and minimal parts count translate to cost savings and
shorter time to market. MICRF008 receiver offers a robust
and low-cost solution for high volume wireless applications.
The MICRF008 sweeps the internal local oscillator at rates
greater than the baseband data rate. This effectively broad-
ens the RF bandwidth of the receiver to a value equivalent to
conventional superregenerative receivers. This allows the
MICRF008 to operate with less expensive LC transmitters
without additional components or tuning, even though the
receiver topology is still superheterodyne. In this mode the
reference crystal can be replaced with a less expensive
±
0.5% ceramic resonator.
Since all post-detection (demodulator) data filtering is pro-
vided on the MICRF008, no external IF filters are required.
One of the two internal filter bandwidths must be externally
selected based on data rate and code modulation format.
