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.
The BC2102 can operate at the 315MHz, 433MHz,
868MHz and 915MHz frequency bands. It supports
both OOK and FSK modulation schemes and can
operate with symbol rate up to 25Kbps and 50Kbps
respectively.
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.
