RO2073E-2 - 3/25/08
Electrical Connections
The SAW resonator is bidirectional and may be installed with either
orientation. The two terminals are interchangeable and unnumbered. The
callout NC indicates no internal connection. The NC pads assist with
mechanical positioning and stability. External grounding of the NC pads is
recommended to help reduce parasitic capacitance in the circuit.
Case Dimensions
Typical Test Circuit
The test circuit inductor, LTEST, is tuned to resonate with the static
capacitance, CO, at FC.
