QwikRadio ? Low-Power UHF Receiver
General Description
The MICRF007 is a single chip, ON-OFF Keyed (ASK/OOK)
Receiver for remote wireless applications, employing Micrel’s
latest QwikRadio ? technology. This device is a true “antenna-in
to data-out” monolithic device. All RF and IF tuning is accom-
plished 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 ?xed at a single frequency
based on an external reference crystal or clock. As with any
conventional superhetrodyne receiver, the companion trans-
mitter ’s frequency must be accurately controlled, generally
with a crystal or SAW (surface acoustic wave) resonator.
The MICRF007 provides two enhancements over the MI-
CRF001/011: (1) a Shutdown Mode, which may be used for
duty-cycle operation, and (2) reduced current consumption.
The MICRF007 requires a mere 2.3mA at 315MHz (3.8mA
at 433.92MHz) when fully operational. These features make
the MICRF007 ideal for low and ultra-low power applications,
such as RKE and RFID.
All post-detection (demodulator) data ?ltering is provided on
the MICRF007, so no external baseband ?lters are required.
The demodulator ?lter bandwidth is ?xed at 2.5kHz. Data
rates up to 3.2kbps NRZ may be used.
All support documentation can be found on Micrel’s web site
at www.micrel.com.
