Micrel's QwikRadio® products are a family of ASK/OOK (amplitude shift keyed/on-off-keyed), highly integrated single-chip RF ICs.
The receivers are true "antenna-in, data-out" devices and the transmitter is an equivalent "data-in, antenna-out" part. Both the transmitter and receivers require no hand-tweaking with trimmer capacitors, as all tuning is performed automatically on-board the devices.
QwikRadio® offers the lowest overall parts-count of any ASK/OOK receivers and transmitters on the market. They are ideal for applications with ranges below 300 feet and data rates below 10Kbps, like handheld controllers and keyFOBs. For longer ranges and higher data rates, check out our RadioWire ® products.
