115kbps, 800MHz - 1GHz UHF Receiver
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
