General Description
The BC2102 is a highly integrated OOK/FSK
transmitter for remote wireless applications. The
transmitter is a true "data-in, antenna-out" monolithic
device making it very easy for users to implement
wireless systems.
BC2102 offers a programmable output power level.
It is capable of delivering +13dBm maximum power
into a 50Ω load. The BC2102 adopts an agile state
machine to ease the control and minimize the power
consumption. With an external crystal and a few
external components, BC2102 can implement a
complete solution for an effective RF transmitter.
These features can be easily programmed through
I²C interface or internal Fuse. With these combined
features the BC2102 can provide a power-saving and
cost effective solution for a huge range of remote
wireless applications.
