General Description

The MICRF007 is a single chip, ON-OFF Keyed (ASK/OOK)

Receiver for remote wireless applications, employing Micrel’s

latest QwikRadio

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 ﬁxed 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 ﬁltering is provided on

the MICRF007, so no external baseband ﬁlters are required.

The demodulator ﬁlter bandwidth is ﬁxed 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.
