The TEMSVA21D334M8R is a surface acoustic wave (SAW) filter manufactured by NEC. SAW filters are electronic components used to selectively filter specific frequencies within a signal. The TEMSVA21D334M8R is designed for use in wireless communication systems, specifically to filter out unwanted signals and noise around a center frequency. This improves the signal-to-noise ratio and overall performance of the communication system.

Applications

• Wireless communication devices: Filtering signals in mobile phones, tablets, and other wireless devices.
• Remote control systems: Selecting the desired frequency in remote control receivers.
• Wireless security systems: Filtering out interference in wireless security sensors and alarms.
• Radio frequency identification (RFID) systems: Enhancing signal reception in RFID readers.
• Global Positioning System (GPS) receivers: Improving signal clarity in GPS devices.

Features

• SAW filter technology: Uses surface acoustic waves to filter signals.
• Narrow bandwidth: Selectively filters a specific frequency range.
• Low insertion loss: Minimizes signal attenuation within the passband.
