Detailed Specs

The TA1637A is typically used at a center frequency around 433.92 MHz. It provides excellent attenuation outside the passband to reject unwanted signals. Insertion loss is generally low, minimizing signal degradation. It's designed for a 50 Ohm impedance system. Due to its small surface mount package it is ideal for compact product designs. Exact specifications will vary slightly between manufacturing lots, consult the relevant datasheet for accurate numbers.

SAW filters like the TA1637A rely on piezoelectric materials to convert electrical signals into mechanical waves, which are then filtered and converted back into electrical signals. This process allows for precise filtering characteristics in a small and cost-effective package. The TA1637A is suitable for demanding applications where performance and size are critical considerations.
