Additional Details:

The TB0190A is designed for a specific center frequency, bandwidth, and impedance, which must be considered when integrating it into a circuit. Key parameters include the insertion loss in the passband, the attenuation in the stopband, the operating temperature range, and the input/output impedance. The device is typically housed in a small surface mount package to minimize board space. The SAW filter's performance characteristics are highly dependent on the specific design and materials used by TAI-SAW. This particular filter exhibits excellent selectivity, allowing it to precisely isolate the desired signal from adjacent interfering frequencies. The stable performance of the TB0190A is crucial for maintaining consistent operation in various environmental conditions. TAI-SAW's expertise in SAW filter design ensures that the TB0190A meets the stringent requirements of modern wireless communication systems. The device's small size makes it ideal for integration into compact, portable devices. Precise frequency filtering helps ensure the correct operation and data transmission and reception of the device.
