Applications Characteristics For the Receivers within Internet of Things and M2M wireless remote control and security devices: | - Operating under ETSI-ETS 300 220 | - That require rejection of strong out-of-band signals (needing, for example, typical out-of-band rejection of 50 dB); | - That may require special rejection at -10.7MHz for local oscillator rejection and special rejection at -21.4MHz for image spurious response for typical superhet receivers.
