RFM RO2023-10
TO39-3 Case
Ideal for European 433.92 MHz Transmitters
Low Series Resistance
Quartz Stability
Rugged, Hermetic, Low-Profile TO39 Case
Complies with Directive 2002/95/EC (RoHS)
The RO2023-10 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-
vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at
433.92 MHz. The RO2023-10 is designed specifically for remote-control and wireless security devices oper-
ating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.

Notes:
1.
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 sub-
sequent 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
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
C
= +25°C±2°C.
The design, manufacturing process, and specifications of this device are sub-
ject 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

)

]. Typically,
oscillator
T
O
is 20°C less than
the specified
resonator
T
O
.
This equivalent RLC model approximates resonator performance near the res-
onant frequency and is provided for reference only. The capacitance C
O
is the
static (nonmotional) capacitance between Pin1 and Pin 2 measured at low fre-
quency (10 MHz) with a capacitance meter. The measurement includes case
parasitic capacitance with a floating case. For usual grounded case applica-
tions (with grund connected to either Pin 1 or Pin 2 and to the case), add
approximately 0.25 pF to C
O
.
