SAW Resonator
LGER433A
The LGER433A is a true one- port ， surface- acoustic- wave( SAW) resonator in a low- profile QCC8C
case. It provides reliable ， fundamental- mode ， quartz frequency stabilization of fixed- frequency
transmitters operating at 433.920 MHz.

NOTES:
1. Frequency aging is the change in fC with time and is specified at +65℃or less. Aging may exceed the specification for
prolonged temperatures above +65℃. Typically, aging is greatest the first year after manufacture, decreasing in subsequent
years.
2. The center frequency, fC ,is the frequency of minimum IL with the resonator in the specified test fixture in a 50 Ω test
system with VSWR ≤ 1.2 : 1. Typically, foscillator or ftransmitter is less than the resonator fC.
3. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility
of the equipment manufacturer.
4. Unless noted otherwise , case temperature TC=+25℃±2℃.
5. The design, manufacturing process, and specifications of this device are subject to change without notice.
6 .Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus
TC , and CO.
7. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO, The nominal center frequency at
any case temperature , TC, may be calculated from :f = fO［1-FTC (TO-TC) 2］.Typically, oscillator TO is 20℃ less than the
specified resonator TO.
8. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for
reference only . The capacitance CO is the measured static (nonmotional) capacitance between either pin 1 and ground or
pin 2 and ground .The measurement includes case parasitic capacitance with a floating case. For usual grounded case
applications (with ground connected to either pin 1 or pin 2 and to the case), add approximately 0.25 pF to CO.
