SAW (surface acoustic wave) filters are electronic passive components used for signal processing in radio frequency (RF) communication systems, consisting of interdigital and standing wave transducers (IDT/SWT) etched on piezoelectric substrates.
The F5QA782M0M2AZ-J is an example of a SAW filter device, which is typically used in a variety of radio communication systems ranging from handheld cellular phones and wireless data systems to land mobile radio systems.
The device is fabricated in a single-ended architecture, incorporating advanced film technologies. It works by trapping frequency components in between the IDT/SWT, thus providing band-pass filtering and signal-shaping functionality.
The device utilizes 96 electrodes and operates over a temperature range of -30°C to +90°C. It is also available as a surface mount component with a maximum insertion loss (MIL) of 1.15dB. It also features high selectivity and high rejection, which makes it ideal for noise suppression applications.
The working principle of the F5QA782M0M2AZ-J SAW filter is based on the physical phenomenon of acousto-electric coupling between an oscillating surface acoustic wave and an electrical circuit. This phenomenon is the result of the inter-conversion of electrical and mechanical energy. When the device is connected to an electrical circuit, the oscillating surface acoustic wave becomes an electrical signal and propagates through the device. The frequency components present in the electrical signal are trapped in between the IDT/SWT, thus providing band-pass filtering and signal-shaping functionality.
SAW filters are widely used in a variety of communication applications due to their low power consumption, high selectivity and high rejection. The F5QA782M0M2AZ-J SAW filter device is suitable for such applications, with its superior electromechanical design providing reliable and efficient performance.
