MICRF008
QwikRadio ? Sweep-Mode Receiver
The MICRF008 QwikRadio UHF receiver is a single-chip
General Description
?
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
broadens 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
Features
Complete UHF receiver on a monolithic chip
300MHz to 440MHz frequency range
Up to 4.8kbps data rate.
Automatic tuning, no manual adjustment
Very low RF antenna reradiation
CMOS logic interface for standard ICs
Low external part count
Replaces superregenerative receivers design
Manufacturability and same performance over the years
Very small PCB area required
Applications
Garage door and gate openers
Security systems
Remote appliances control
Toys
Fan and light control
provided 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.
