A High Performance, Single-SAW SDARS SolutionIntroducing Guerrilla RF's new Satellite Digital Audio Radio Service (SDARS) solution for non-collocated cellular transmit applications. In this operating environment, the difficult out-of-band blocker (OOB) specification is reduced significantly from +10 dBm to -10 dBm. This relaxation of the OOB blocker spec makes it possible to have a spec-compliant LNA solution which uses only a single surface acoustic wave (SAW) filter.
