The RO3156E-3 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 fixed-frequency transmitters  
operating at 868.95 MHz.This SAW is designed specifically for remote-control and wireless security  
transmitters operating under ETSI EN 300 220.

Notes:

2.  
Frequency aging is the change in fC with time and is specified at +65 °C or less.  
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.  
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.  
8.  
The center frequency, fC, is measured at the minimum insertion loss point, ILMIN  
,
with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt  
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically,  
9.  
fOSCILLATOR or fTRANSMITTER is approximately equal to the resonator fC.  
3.  
4.  
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.
