Ultra-Small GNSS Antenna Module Integrates LNA And SAW

Antenova’s latest module for tiny positioning devices, the RADIONOVA M20047-1, is an active antenna module for GNSS applications in the 1,559 to 1,609 MHz satellite bands using GPS, GLONASS, GALILEO or BeiDou. The M20047-1 antenna module consists of an SMD antenna with built-in active components, an LNA filter and SAW, all contained in a compact FR4 part measuring 7 mm x 7 mm x 0.9 mm and weighing less than 2g.

 

The on-board LNA and filter act to boost the signal to the GNSS processor in environments where there is a restricted view of the sky or where line-of-sight to the horizon is difficult. Antenova has also added an external matching feature to compensate for any de-tuning of the antenna caused by proximity to other components, such as a plastic case or a battery. The clear-out area required by the antenna module is 7 mm x 5 mm. For more info and a datasheet, visit Antenova.
