SAW Devices

The reduced level of unnecessary signals.


The frequency width of unnecessary signals to be reduced.

Electronic component which allows a range of specified frequencies to pass.


Abbreviation of Electromagnetic Compatibility. The concept of enabling electronic devices to function without EMI.

Abbreviation of Electromagnetic Interference. A disturbance of an electrical circuit caused by external interference of an electromagnetic origin.

Abbreviation of Electromagnetic Susceptibility. The vulnerability of an electric circuit to a disturbance of electromagnetic origin.

Abbreviation of Frequency Division Duplex. The duplex which realizes simultaneous communication of Tx and Rx by using different frequency bands.

The opposition to current flow in a circuit, including resistance, inductance, and capacitance.

The loss of signal power resulting from the insertion of a device in a transmission line or optical fiber.


Signal division between Tx (Transmit) and Rx (Receive).

Electronic component which amplifies low-power signals without degrading its signal-to-noise ratio.

Technology which prints fine patterns on a wafer by certain exposure treatments during development. Features high accuracy and mass production capability.

Electronic component which amplifies a signal to achieve a higher frequency for transmission.

A soldering method in which solder is applied to electronic components and then melted in a reflow oven to permanently mount them to a printed circuit board (PCB).

Gap between the highest point and lowest point of loss within a passband.


Electronic component which isolates Tx and Rx signals by applying a surface acoustic wave.

Abbreviation of Surface Mount Device. Components suitable for SMT equipment.

Abbreviation of Surface Mount Technology. A method of producing electronic circuits on a printed circuit board (PCB) by applying solder paste and placing components on the PCB's surface before the solder is melted in a reflow oven.


Abbreviation of Time Division Duplex. The duplex which realizes simultaneous communication by dividing the band into different time slots, switching between Tx and Rx in high speed.

Abbreviation of Voltage Standing Wave Ratio. A measure of how efficiently radio-frequency power is transmitted from a power source, through a transmission line, into a load.
