RO3073E-1
?
Ideal for 315 MHz Automotive-Keyless-Entry Transmitters
? Very Low Series Resistance
? Quartz Stability
? Complies with Directive 2002/95/EC (RoHS) Pb
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.

Frequency aging is the change in f C 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.
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 induc-
tance, L TEST , is tuned for parallel resonance with C O at f C . Typically, f OSCILLA-
TOR or f TRANSMITTER is approximately equal to the resonator 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 govern-
ment approval, which is the responsibility of the equipment manufacturer.
Unless noted otherwise, case temperature T C = +25°C±2°C.
The design, manufacturing process, and specifications of this device are subject
to change without notice.

Derived mathematically from one or more of the following directly measured
parameters: f C , IL, 3 dB bandwidth, f C versus T C , and C O .
Turnover temperature, T O , is the temperature of maximum (or turnover) fre-
quency, f O . The nominal frequency at any case temperature, T C , may be calcu-
lated from: f = f O [1 - FTC (T O -T C ) 2 ]. Typically oscillator T O is approximately
equal to the specified resonator T O .
This equivalent RLC model approximates resonator performance near the reso-
nant frequency and is provided for reference only. The capacitance C O 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:
C P ≈ C O - 0.05 pF.
Tape and Reel Standard Per ANSI / EIA 481.
