Holtek Semiconductor BC2102
The BC2102 is a low cost sub-GHz OOK/FSK transmitter for wireless applications in the 315MHz, 433MHz, 470MHz, 868MHz and 915MHz frequency bands. It is a highly integrated and low cost solution for one-way transmitters. It only needs a crystal, a few external capacitors and a few PA output matching components on PCB to form a complete RF solution.| Part No. | BC2102 |
