Applications
The MICRF002 is designed for short-range wireless receiver applications such as remote keyless entry systems, garage door openers, security alarms, and home automation. Its fully integrated architecture simplifies antenna interface and requires only a few passive components to build a complete receive front-end. The wide 300 MHz to 440 MHz tuning range lets designers target multiple ISM sub-bands with a single chip.

Frequently Asked Questions
What frequency range does the MICRF002 cover, and which ISM bands does that include?
The MICRF002 tunes across 300 MHz to 440 MHz, which encompasses the 315 MHz and 433.92 MHz ISM sub-bands commonly used for short-range devices in North America and Europe. This wide range lets a single board design be re-tuned for either region by adjusting only the external LC tank components.
Which modulation scheme does the MICRF002 support, and what limits its maximum data rate?
The MICRF002 supports ASK and OOK modulation exclusively, with a built-in data slicer that recovers baseband data at rates up to a few kbps depending on the AGC time constant. For protocols using Manchester encoding at 2 kbps, the device comfortably meets bit-error performance across the 300 MHz to 440 MHz band.
How does the MICRF002's 16-pin SOIC package compare to DIP options in terms of board space, and how many external components are typically needed?
The 16-pin SOIC body measures approximately 9.9 mm x 3.9 mm, roughly half the footprint of a 16-pin DIP (19.05 mm row pitch), making it preferable for compact PCB designs. A typical application circuit requires only a matching inductor, a few bypass capacitors, and a data-filter RC network — typically under 10 external passives — which keeps BOM count and assembly cost low.
