The MICRF007 is a single chip ASK/OOK (ON-OFF Keyed)
Receiver IC for remote wireless applications, employing
Micrel’s latest QwikRadiotm technology. 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 extremely low cost solution.
The MICRF007 is an enhanced version of the MICRF002 and
MICRF011.
The MICRF007 is a conventional superhetrodyne receiver,
with an (internal) Local oscillator fixed at a single frequency
based on an external reference crystal or clock. As with any
conventional superhetrodyne reciever, the transmit frequency
must be accurately controlled, generally with a crystal or
SAW (Surface Acoustic Wave) resonator.
The MICRF007 provides two feature enhancements over the
MICRF001/011, (1) a Shutdown Mode, which may be used
for duty-cycle operation. (2) Reduced current consumption.
The MICRF007 requires a mere 1.7mA at 315MHz (3.0mA at
433.92MHz).These features make the MICRF007 ideal for
low and ultra-low power applications, such as RKE and RFID.
All post-detection (demodulator) data filtering is provided on
the MICRF007, so no external baseband filters are required.
The demodulator filter bandwidth is set to 2.1kHz. Data rates
up to 2kbps may be used.
