This paper studies about design of a transceiver using a single PLL. The transceiver has bandwidth of 424.7 ~ 424.95 MHz and the communication method used 21 channels 12.5 KHz channel bandwidth and FSK modulation/demodulation method. Also, we designed low power wire1ess transceiver for data transmission using a single PLL. Finally, the transceiver set achieves the following characteristics : 8.l5dBm output power, 45.97dBc spurious property
