The RO3073E-1 is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic
case. It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at
approximately 315 MHz. This SAW was designed for AM transmitters in automotive-keyless-entry applica-
tions operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.

Notes:
1.
Frequency aging is the change in fC with time and is specified at +65°C or less.
Aging may exceed the specification for prolonged temperatures above +65°C.
Typically, aging is greatest the first year after manufacture, decreasing in subse-
quent years.
2.
The center frequency, fC, is measured at the minimum insertion loss point, ILMIN,
with the resonator in the 50
test system (VSWR ≤ 1.2:1). The shunt induc-
tance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOSCILLA-
TOR or fTRANSMITTER is approximately equal to the resonator fC.
3.
One or more of the following United States patents apply: 4,454,488 and
4,616,197.
4.
Typically, equipment utilizing this device requires emissions testing and govern-
ment approval, which is the responsibility of the equipment manufacturer.
5.
Unless noted otherwise, case temperature TC = +25°C±2°C.
6.
The design, manufacturing process, and specifications of this device are subject
to change without notice.
7.
Derived mathematically from one or more of the following directly measured
parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
8.
Turnover temperature, TO, is the temperature of maximum (or turnover) fre-
quency, fO. The nominal frequency at any case temperature, TC, may be calcu-
lated from: f = fO [1 - FTC (TO -TC)
2]. Typically oscillator T
O is approximately
equal to the specified resonator TO.
9.
This equivalent RLC model approximates resonator performance near the reso-
nant frequency and is provided for reference only. The capacitance CO is the
static (nonmotional) capacitance between the two terminals measured at low fre-
quency (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:
CP ≈ CO -0.05pF.
