MICRF002/RF022  
300-440MHz QwikRadio® ASK Receiver  
General Description  
The MICRF002 is a single chip ASK/OOK (ON-OFF  
Keyed) RF receiver IC. This device is a true “antenna-in to  
data-out” monolithic device. All RF and IF tuning is  
accomplished automatically within the IC which eliminates  
manual tuning and reduces production costs. The result is  
a highly reliable yet low cost solution.  
QwikRadio®  
Features  
300MHz to 440MHz frequency range  
Data-rate up to 10kbps (fixed-mode)  
Low Power Consumption  
2.2mA fully operational (315MHz)  
0.9µA in shutdown  
The MICRF002 is a fully featured part in 16-pin packaging,  
the MICRF022 is the same part packaged in 8-pin  
packaging with a reduced feature set (see “Ordering  
Information” for more information).  
The MICRF002 is an enhanced version of the MICRF001  
and MICRF011. The MICRF002 provides two additional  
functions over the MICRF001/011, (1) a Shutdown pin,  
which may be used to turn the device off for duty-cycled  
operation, and (2) a “Wake-up” output, which provides an  
output flag indicating when an RF signal is present. These  
features make the MICRF002 ideal for low and ultra-low  
power applications, such as RKE and remote controls.  
220µA in polled operation (10:1 duty-cycle)  
Wake-up output flag to enable decoders and  
microprocessors  
Very low RF re-radiation at the antenna  
Highly integrated with extremely low external part count  
Applications  
All IF filtering and post-detection (demodulator) data  
filtering is provided within the MICRF002, so no external  
filters are necessary. One of four demodulator filter  
bandwidths may be selected externally by the user.  
Automotive remote keyless entry (RKE)  
Remote controls  
Remote fan and light control  
Garage door and gate openers  
The MICRF002 offer two modes of operation; fixed-mode  
(FIX) and sweep-mode (SWP). In fixed-mode the  
MICRF002 functions as a conventional superhet receiver.  
In sweep-mode the MICRF002 employs a patented  
sweeping function to sweep a wider RF spectrum. Fixed-  
mode provides better selectivity and sensitivity  
performance and sweep-mode enables the MICRF002 to  
be used with low cost, imprecise transmitters.
