SAW Resonator  
The RO3144E-3 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  
916.650 MHz. This SAW is designed specifically for remote-control and data-link transmitters operating in  
the USA under FCC Part 15 regulations.

Notes:

2.  
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.  
7.  
Derived mathematically from one or more of the following directly measured parameters: fC  
IL, 3 dB bandwidth, fC versus TC, and CO  
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 TO is approximately equal to the specified resonator TO  
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.

.
8.  
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.  
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 TC = +25°C±2°C.  
The design, manufacturing process, and specifications of this device are subject to change  
without notice.
