The RO2166E 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 local oscillators operating at 857.65
MHz. This SAW is designed for 857.65 MHz superhet receivers with 10.7 MHz IF. Applications include
remote-control and wireless security receivers operating under ETSI-ETS 300 220 in Europe and under FTZ
17 TR 2100 in Germany.

Notes:
1. Frequency aging is the change in fC with time and is specified at +65°C or less.
parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
Aging may exceed the specification for prolonged temperatures above +65°C. 8. Turnover temperature, TO, is the temperature of maximum (or turnover) fre-
Typically, aging is greatest the first year after manufacture, decreasing in subse-
quency, fO. The nominal frequency at any case temperature, TC, may be calcu-
quent years.
2. The center frequency, fC, is measured at the minimum insertion loss point,
ILMIN, with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOS-

equal to the specified resonator TO.
