MICRF102 Datasheet | Micrel Semiconductor

Description The MICRF102 is a single chip Transmitter IC for remote wireless applications. The device employs Micrel’s latest Qwik Radio™ technology. This device is a true “data-in, antennaout” monolithic device. All antenna tuning is acplished automatically within the IC which eliminates manual tuning, and reduces production costs. The result is a highly reliable yet extremely low cost solution for high volume wireless applications. Because the MICRF102 is a true single-chip radio transmitter, it is easy to apply, minimizing design and production costs, and improving time to market. The MICRF102 uses a novel architecture where the external loop antenna is tuned to the internal output stage. This transmitter is designed to ply with worldwide UHF unlicensed band intentional radiator regulations. The IC is patible with virtually all ASK/OOK (Amplitude Shift Keying/On-Off Keyed) UHF receiver types from wide-band super-regenerative radios to narrow-band, high performance super-heterodyne receivers. The transmitter is designed to work with transmitter data rates from 100 to 20k bits per second. The automatic tuning, in conjunction with the external resistor, ensures that the transmitter output power stays constant for the life of the battery. When used with Micrel’s family of Qwik Radio™ receivers, the MICRF102 provides the lowest cost and most reliable remote actuator and RF link system available.
