Resonator

The RO2104 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-

vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at

303.825 MHz (often referred to as the 303.875 MHz channel). The RO2104 is designed for remote-control

and wireless security transmitters operating in the USA under FCC Part 15, in Japan, in Australia, and in

Korea.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.

Notes:

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

7. Derived mathematically from one or more of the following directly measured

parameters: f_C, IL, 3 dB bandwidth, f_Cversus T_C, and C_O.

8. Turnover temperature, T_O, is the temperature of maximum (or turnover) fre-

quency, f_O. The nominal frequency at any case temperature, T_C, may be calcu-

lated from: f = f_O[1 - FTC (T_O-T_C)²]. Typically, oscillator T_Ois 20°C less than

the specified resonator T_O.

9. This equivalent RLC model approximates resonator performance near the reso-

nant frequency and is provided for reference only. The capacitance C_Ois the

Aging may exceed the specification for prolonged temperatures above +65°C.

Typically, aging is greatest the first year after manufacture, decreasing signifi-

cantly in subsequent years.

2. The center frequency, f_C, is measured at the minimum insertion loss point, IL_MIN

with the resonator in the 50 W test system (VSWR £ 1.2:1). The shunt induc-

tance, L_TEST, is tuned for parallel resonance with C_Oat f_C. Typically, f_OSCILLA-

_TORor f_TRANSMITTERis less than the resonator f_C.

3. One or more of the following United States patents apply: 4,454,488 and

4,616,197 and others pending.

4. Typically, equipment designs utilizing this device require emissions testing and

government approval, which is the responsibility of the equipment manufacturer.

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.

static (nonmotional) capacitance between pin1 and pin 2 measured at low fre-

quency (10 MHz) with a capacitance meter. The measurement includes case

parasitic capacitance with a floating case. For usual grounded case applica-

tions (with ground connected to either pin 1 or pin 2 and to the case), add

approximately 0.25 pF to C_O.
