Resonator  
The RO2150A 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 oscillators operating  
at 304.0 MHz. The RO2150A is designed for wireless remote-control transmitters operating in Japan and  
Australia

Frequency aging is the change in fC with time and is specified at +65°C or less.

Turnover temperature, TO, is the temperature of maximum (or turnover) fre-  
quency, fO. The nominal frequency at any case temperature, TC, may be calcu-  
lated 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 reso-  
nant 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 para-  
sitic capacitance with "NC” pads unconnected. Case parasitic capacitance is  
approximately 0.05 pF. Transducer parallel capacitance can by calculated as:  
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, fC, is measured at the minimum insertion loss point,  
9.  
ILMIN, with the resonator in the 50 W test system (VSWR £ 1.2:1). The shunt  
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOS-  
CILLATOR 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 govern-  
ment 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.
