Crystals play a major role in modern communication technology due to their ability to precisely control the electrical properties of devices. In particular, small surface acoustic wave (SAW) devices are used for radio frequency (RF) filtering, timing, and other applications. The SSPT7F-12.5PF10PPM crystal is a 12.5 pF SAW filter with an insertion loss of less than 1.5 dB and a stopband rejection of 28 dB. This type of device is designed for use in wireless LAN and GPS systems.

The SSPT7F-12.5PF10PPM crystal is based on a two-port network consisting of two transducers, which convert electrical signals into surface acoustic waves and vice versa. The transducers are fabricated using thin film and vapor deposition processes, and they are connected to electrodes that form the input and output ports of the filter. The filter is tuned by controlling the capacitance of the two electrodes and the frequency of the filter is determined by the propagation velocity of the surface acoustic wave (SAW) along the substrate. Depending on the circuit configuration, the filter can either provide a low pass or a high-pass response.

The SSPT7F-12.5PF10PPM crystal is designed for use in wireless LAN systems, as well as in GPS systems. This type of device is typically used as a filter to separate the antenna input from the transceiver output. The filter also helps reduce the out-of-band noise and interference, as well as improve the signal-to-noise ratio of the received signal. Moreover, the filter is also used to provide timing signals in GPS receivers, which are used to accurately determine the location of the receiver. The filter is designed to be highly stable and accurate, with a frequency stability of 10 ppm over the operating temperature range of -20 to +85 °C.

The SSPT7F-12.5PF10PPM crystal is a high-performance device based on a SAW filter coupled with custom thin-film transducers. The device offers a low insertion loss, high stopband rejection, and excellent frequency stability, making it suitable for use in a variety of radio frequency applications, including wireless LAN and GPS systems. Furthermore, the device is designed for use in harsh environments and is able to withstand a wide range of temperatures without loss of performance.
