Product Description
CC1050 is a true single-chip UHF transmitter
designed for very low power and
very low voltage wireless applications. The
circuit is mainly intended for the ISM
(Industrial, Scientific and Medical) and
SRD (Short Range Device) frequency
bands at 315, 433, 868 and 915 MHz, but
can easily be programmed for operation at
other frequencies in the 300-1000 MHz
range.
The main operating parameters of CC1050
can be programmed via an easy-tointerface
serial bus, thus making CC1050 a
very flexible and easy to use transmitter.
In a typical system CC1050 will be used
together with a microcontroller and a few
external passive components.
CC1050 is based on Chipcon’s SmartRF®
technology in 0.35 μm CMOS.
