Lifetime (10 year) frequency aging.
The center frequency, f
C
, is measured at the minimum insertion loss point,
IL
MIN
, with the resonator in the 50
test system (VSWR
≤
1.2:1). The shunt
inductance, L
TEST
, is tuned for parallel resonance with C
O
at f
C
.
One or more of the following United States patents apply: 4,454,488 and
4,616,197.
Typically, equipment utilizing this device requires emissions testing and gov-
ernment approval, which is the responsibility of the equipment manufacturer.
Unless noted otherwise, case temperature T

= +25°C±2°C.
The design, manufacturing process, and specifications of this device are sub-

This equivalent RLC model approximates resonator performance near the
resonant frequency and is provided for reference only. The capacitance C
O
is
the static (nonmotional) capacitance between the two terminals measured at
low frequency (10 MHz) with a capacitance meter. The measurement
includes parasitic capacitance with”NC” pads unconnected. Case parasitic
capacitance is approximately 0.05 pF. Transducer parallel capacitance can
by calculated as: C
P
≈
C
O
- 0.05 pF.
