MICRF002/RF022

300-440MHz QwikRadio™ASK Receiver

Final Information

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.

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.

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.

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.
