WIRELESS RECEIVING DEVICE WITHOUT PLL FREQUENCY SYNTHESIZER AND WIRELESS RECEIVING METHOD USING THE SAME |
摘要 |
A receiver implemented without using a phase locked loop frequency synthesizer and a receiving method of a receiver implemented without using a phase locked loop frequency synthesizer are provided. The receiver includes a radio frequency (RF) receiving unit; a band-selecting unit (310); an RF amplifier (320); a low oscillation (LO) signal generator (380); a mixer (330); an IF amplifier (340); an analog to digital (A/D) converter (350); and a channel-selecting unit (360). The method includes passing (S502) a frequency band of a radio frequency (RF) signal received by an RF receiving unit; amplifying (S504) the passed RF signal; generating (S506) a low oscillation (LO) signal having a fixed frequency; mixing the LO signal with the amplified RF signal to lower the frequency of the amplified RF signal; outputting an intermediate frequency (IF) signal; amplifying (S508) the IF signal; converting (S510) the amplified IF signal into a digital signal; and selectively passing (S512) frequencies of the digital signal corresponding to a specific channel. |
