RO2073A-6 - 1/7/10
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.
Typical Test Circuit
The test circuit inductor, LTEST, is tuned to resonate with the static
capacitance, CO, at FC.
Typical Application Circuits
Equivalent LC Model
Temperature Characteristics
The curve shown on the right
accounts for resonator
contribution only and does not
include LC component
temperature contributions
.

Board
Land Pattern
The circuit board land pattern shown below is one possible design. The
optimum land pattern is dependent on the circuit board assembly process
which varies by manufacturer. The distance between adjacent land edges
should be at a maximum to minimize parasitic capacitance. Trace lengths
from terminal lands to other components should be short and wide to
minimize parasitic series inductances.
Case Design
The case material is black alumina with contrasting symbolization. All pads
are nominally centered with respect to the base and consist of 40 to
70 microinches electroless gold on 60-350 micorinches electroless nickel.
