Resonator
The RP1032 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-
vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency oscillators operating at or
near 674 MHz. Typical applications include the second LO in CATV set-top convertors with channel 3 output.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1. Frequency aging is the change in f with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above
C
+65°C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
2. The frequency f is the frequency of minimum IL with the resonator in the specified test fixture in a 50 W test system with VSWR £ 1.2:1. Typically, f

is less than the resonator f .

Equivalent LC Model
This two-port, three-terminal SAW resonator is bidirectional. However, im-
pedances and circuit board parasitics may not be symmetrical, requiring
slightly different oscillator component-matching values.
