1. the art that the invention defined in the claims The present invention will on a very high frequency transceiver. 2. The invention attempts to solve the technical challenges The present invention is the design of the RF (Radio Frequency) it is possible to use the band and the IF (Intermediate Frequency) the same voltage controlled oscillator and PLL (Phase Locked Loop) in the band simply configure the transmitting and receiving apparatus, reducing also the components necessary to design products reducing the cost, one-can minimize the chip area when making the chip (One-chip), the different frequencies of the IF frequency and the voltage controlled oscillator design at the receiving end very high frequency, which can reduce effects on the DC offset (offset) intended to provide a transmitting and receiving device. 3. Resolution of the subject matter of the invention, The invention receiving means for receiving a received signal from antenna outputs an intermediate frequency (IF) and then converts the demodulated baseband signal to the baseband modem (Baseband Modem) generated in the common local signal generating means; Transmission means for transmitting to and modulates the signal output from the baseband modem (Baseband Modem) converted into a signal of RF (Radio Frequency) band generated by the common local signal generating means through the antenna; And including the common local signal generating means for generating a predetermined frequency required for an intermediate frequency (IF) band of the RF band and the receiving means of the transmission means. 4. An important use of the invention, The invention yiyongdoem the like communication systems.
