Resonator  
The RP1286 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 905.8 MHz. This resonator is designed specifically for use in the local oscillator of 916.5 MHz superhet-  
erodyne receivers operating in the USA under FCC Part 15.249 and in Canada under DoC RSS-210. It is  
also suitable for a variety of other oscillator applications.

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  
C
above +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
or f  
is less than the resonator f .
