The RO3144D is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case.
It provides reliable, fundamental-mode stabilization of fixed-frequency transmitters operating at 916.5 MHz.
This SAW is designed specifically for remote-control and data-link transmitters operating in the USA under
FCC Part 15 regulations.

F requency 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 Ω test system (VSWR ≤ 1.2:1). The shunt
inductance, L TEST , is tuned for parallel resonance with C O at f C . Typically,
f OSCILLATOR 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
government 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)
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
approximately equal to the specified resonator T O .
This equivalent RLC model approximates resonator performance near the
resonant frequency and is provided for reference only. The capacitance C O 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:
C P ≈ C O - 0.05 pF.
Tape and Reel Standard Per ANSI/EIA 481.
