WebIn a low-IF receiver, the RF signal is mixed down to a non-zero low or moderate intermediate frequency, typically a few megahertz (instead of 33–40 MHz) for TV, and even lower frequencies (typically 120–130 kHz instead of 10.7–10.8 MHz or 13.45 MHz) in the case of FM radio band receivers or (455–470 kHz for) AM (MW/LW/SW) receivers. … WebThe main difference among GNSS receivers falls into the specific characteristics that have impact at RF level, such as the Multiple Access Techniques employed. GPS (as Galileo and BeiDou) uses a CDMA technique allowing a simpler RF module (than for example GLONASS), since all signals in the same frequency band have a common carrier. WebFM receivers use the superheterodyne principle, as shown in Figure 9-1. Recall that a superhet receiver operates by converting the desired incoming RF carrier frequency down to the IF or intermediate frequency, where most of the amplification is provided and receiver bandwidth is defined.
