ACTIVE ANTENNAS
TECHNOLOGY OVERVIEW
BAND SWITCHING
With design complexity increasing every day, AVX’s patented RF
band switching technology is ideal for meeting harsh specifications
when the environment reduces the original bandwidth. The reduction
could be caused by the presence of metallic components, wires,
harnesses, heatsink, other antennas, LCD, shielding cans, PCB
grounding and connectors. Typical band switching architectures
use 4 switching states in the low band operations and one state in
the high band.

ACTIVE COMPONENTS FOR BAND SWITCHING
Active switching technology benefits include: longer range, higher throughput and broader signal coverage. Connection
dead spots are reduced as the RF switch and antenna are designed together, allowing for a more flexible antenna system
placement and development in the device. Link optimization is obtained through a band switching concept that allows
simpler and smaller antenna architecture to cover a wider bandwidth.
