Typical Application Circuit Diagram – PND Application with Co-Located Interference Sources

This is a two-SAW circuit with provision for a switched external active antenna. Both a front-end SAW (for the internal antenna) and a further inter-stage SAW filter

are included for acceptable blocking performance in a co-located interferer environment (e.g. WLAN or cellphone).
