Applications and Data of SAW Resonator

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.

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.
