Product Description
is a true single-chip UHF trans-
In a typical system

external passive components.
will be used
ceiver 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 433, 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.
is based on Chipconís SmartRF -
02 technology in 0.35 µm CMOS.
The
narrowband
is especially suited for
systems with channel
spacings of 50 kHz and higher complying
with EN 300 220 and FCC CFR47 part 15.
The
main operating parameters
can be programmed via a serial bus, thus
making a very flexible and easy to
use transceiver.
