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.
