Applications and Data of SAW Resonator
s
Application
SAW RESONATER has generally 2 types of 1-port type and
2-port type.
1-port SAW RESONATOR is basically a 2 terminal device
and its application is similar to that of quartz bulk wave
resonator or ceramic resonator. Most of the application
circuit is Colpitts or similar type that can be made with low
cost. 1-port SAW RESONATOR is also applicable to VCO
(Voltage Controlled Oscillator) application.
2-port SAW RESONATOR is a kind of very narrow, low loss
band-pass filter. Oscillation circuit is mostly like a RF
amplifier with feedback loop.
SARCC series is 1-port SAW RESONATOR. Later
application data is oscillation circuit by 1-port SAW
RESONATOR.
s
Basic structure of 1-port SAW RESONATOR
1-port SAW RESONATOR has one IDT (Inter Digital
Transducer), which generates and receives SAW, and two
grating reflectors, which reflect SAW and generate a
standing wave between the two reflectors. IDT and
reflectors are fabricated on quartz crystal substrate by
photolithographic process. Cut angle of the substrate shall
be selected carefully. SAW RESONATOR chip is
encapsuled in a ceramic package.
