Why is the Local Oscillator Frequency Always Higher Than the Signal Frequency? Introduction to Local Oscillator and Signal Frequency In the realm of communication systems, the concepts of local oscillator (LO) frequency and signal frequency are fundamental. A local oscillator is an electronic oscillator used within both receivers and transmitters to generate a signal at …

Understanding the Frequency Range of the Ku-Band Introduction to the Ku-Band The Ku-band represents a segment within the electromagnetic spectrum encompassing microwave frequencies, specifically between 12 and 18 GHz. Originating from the designation ‘Ku’, which stands for ‘Kurz-unten,’ translating from German to ‘shortened below,’ this band is named to reflect its position in comparison to …
How Does a Local Oscillator Work? Introduction to Local Oscillators A local oscillator (LO) is a pivotal component in various electronic devices, particularly those involved in communication systems. At its core, a local oscillator generates a specific frequency signal, which is crucial in the manipulation and processing of incoming signals. The primary role of a …
