Integer boundary spurious

NettetIt is because unwanted emissions of high power transmitters under modulated conditions have to be below the spurious limit (70 dBc) at the boundary between the OoB and spurious domains. Also, if future systems in the fixed service operating in this frequency range require a necessary bandwidth larger than 12 kHz, it may become necessary to … NettetThe spurious signals seen half way between the integer boundaries (2049 MHz and 2051 MHz in Figure 1) are second-order integer boundary spurs. Second-order integer boundary spurs occur halfway between integer boundaries. Typically, second-order IBS …
