Receiver without phase locked loop frequency synthesizer and 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; an RF amplifier; a low oscillation (LO) signal generator; a mixer; an IF amplifier; an analog to digital (A/D) converter; and a channel-selecting unit. The method includes passing a frequency band of a radio frequency (RF) signal received by an RF receiving unit; amplifying the passed RF signal; generating 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 the IF signal; converting the amplified IF signal into a digital signal; and selectively passing frequencies of the digital signal corresponding to a specific channel.
