Spurious response sensitivity of two-way transceivers related to the 3rd-order nonlinearity of SAW filters
The spurious response sensitivities (SRSs) of two-way radio transceivers, as determined from the 3rd-order nonlinearities of SAW filters, are compared using two types of filter, the IIDT-type and a newly-developed SAW-resonator-coupled type, in high-power (~1 W) applications. The latter type is shown to result in an SRS which satisfies system specifications with sufficient margins.
