Product Description
CC1070 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 402, 424, 426, 429, 433, 447,
449, 469, 868 and 915 MHz, but can
easily be programmed for multi-channel
operation at other frequencies in the 402 -
470 and 804 - 940 MHz range.
The CC1070 is especially suited for narrowband
systems with channel spacings of
12.5 or 25 kHz complying with ARIB STD
T-67 and EN 300 220.
The CC1070 main operating parameters
can be programmed via a serial bus, thus
making CC1070 a very flexible and easy to
use transmitter. In a typical application
CC1070 will be used together with a
microcontroller and a few external passive
components.
