The RO2073A-6 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 fixed-frequency transmitters
operating at 315.0 MHz. This SAW is designed for AM transmitters in automotive keyless-entry applications
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 subsequent 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
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOSCILLATOR 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 government 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) frequency, fO. The nominal frequency at any case temperature, TC, may be
calculated 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 resonant frequency and is provided for reference only. The capacitance CO
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: CP ≈ CO -0.05 pF.
