Resonator

The RO2073 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

315 MHz. The RO2073 is designed specifically for wireless remote controls and security transmitters, typi-

cally for automotive-keyless-entry, operating in the USA under FCC Part 15, in Canada under DoC RSS-210,

and in Italy.

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-

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

cantly in subsequent years.

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.
