A miniature TCXO for GPS/GNSS application

Abstract

Temperature compensated crystal oscillators (TCXOs) are widely used for mobile communication systems such as personal navigation devices (PNDs) and cell phones. Recently, wearable devices strongly require electronic components inside them to be smaller and thinner. Besides, the close-in phase noise and overall frequency stability also need be considerated for GPS/GNSS application. Therefore, this paper demonstrates the ultra-miniature size TCXO with H-type package to meet such requirements.
