Technical Specifications

While precise specifications require referencing the official EPCOS (TDK) datasheet for the W1020, typical SAW filter parameters include center frequency, bandwidth, insertion loss, ripple, and rejection. These parameters define the filter's ability to pass the desired signal while attenuating unwanted signals. The operating temperature range and impedance matching characteristics are also critical specifications.

SAW filters like the W1020 utilize piezoelectric materials to convert electrical signals into mechanical waves on the surface of the device and then back into electrical signals. This process allows for precise filtering characteristics to be achieved. The design and manufacturing of SAW filters require specialized expertise and equipment to ensure optimal performance. EPCOS (TDK) is a leading manufacturer of SAW filters, known for their high quality and reliability.
