Radio tranceiver for data communications

摘要: A compact low-power radio frequency (RF) transceiver with a built-in antenna provides wireless communication between computer and another device. direct conversion receiver together voltage controlled oscillator, phase lock loop circuits, digitally divider circuits patch are packaged into enclosure, having dimensions within the PCMCIA format. In some embodiments, enters sleep mode whenever it is idle in order to further conserve power. other signature detector enables distinguish noise valid messages by recognizing word embedded data packet.
