Ideal for 913.5 MHz FCC Part 15.249 Transmitters
Nominal Insertion Phase Shift of 180
°
at Resonance
Quartz Stability
Rugged, Hermetic, Low-Profile TO39 Case
The RP1261 is a two-port, 180
°
surface-acoustic-wave (SAW) resonator in a low-pro-
file TO39 case. It provides reliable, fundamental-mode, quartz frequency stabilization
of fixed-frequency oscillators and transmitters operating at 913.5 MHz. This resonator
was designed specifically for use in low-power transmitters operating in the USA
under FCC Part 15.249 regulations and in Canada under DoC RSS-210.
CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
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 subsequent years.
2. The frequency f
C
is the frequency of minimum IL with the resonator in the specified test fixture in a 50
test system with VSWR
≤
1.2:1. Typically,
f
OSCILLATOR
or f
TRANSMITTER
is less than the resonator f
C
.
3. One or more of the following United States patents apply: 4,454,488; 4,616,197.
4. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufac-
turer.
5. Unless noted otherwise, case temperature T
C
= +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: f
C
, IL, 3 dB bandwidth, f
C
versus T
C
, and C
O
.
8. Turnover temperature, T
O
, is the temperature of maximum (or turnover) frequency, f
O
. The nominal frequency at any case temperature, T
C
, may be
calculated from: f = f
O
[1 - FTC (T
O
- T
C
)
2
]. Typically,
oscillator
T
O
is 20° less than the specified
resonator
T
O
.
9. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance
C
O
is the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case para-
sitic capacitance.
