Final Information

General Description

The MICRF005 QwikRadio™ UHF receiver is a single-chip

OOK (on-off keyed) receiver IC for remote wireless applica-

tions. This device is a true single-chip, “antenna-in, data-out”

device. All RF and IF tuning is accomplished automatically

within the IC which eliminates manual tuning production

costs and results in a highly reliable, extremely low-cost

solution for high-volume wireless applications.

The MICRF005 provides two additional key features: (1) A

transmit standby mode, and (2) a shutdown mode which may

be used for duty-cycle operation. These features make the

MICRF005 ideal for low power applications in both one-way

and bi-directional wireless links.

All IF and post-detection (demodulator) data filtering is pro-

vided on the MICRF005, no external filters are required.

Nominal filter bandwidth is fixed a 300kHz allowing a data

throughput at rates up to 115kbps.

Features

• 800MHz to 1000MHz frequency range

• Data rates up to 115kbps

• No filters or inductors required

• Low 10mA operating supply current at 868MHz

• Shutdown mode for >10:1 duty-cycle operation

• Very low RF antenna re-radiation

• CMOS logic interface for standard ICs

• Extremely low external part count

• Transmit standby mode for bi-directional link control

Applications

• Wireless game controllers

• Security systems

• Medium-rate data modems
