Demonstrates high performance and low cost to meet the demands of future 5G networks
The demand for low-cost, high-performance radio frequency (RF) components is accelerating, driven in part by the needs of 5G networks.
Researchers at Purdue University have demonstrated a high-Q tunable bandpass filter machined from ABS plastic. It
shows a high-Q from 500 to 700 and a 91% tuning range from 2.2 to 4.2 GHz. Production
can be scaled up using injection molding.
The machined prototype uses an M3-L Linear Actuator from New Scale Technologies for tuning. For mass production, New Scale's UTAF Ultra-Thin Acutator Family can provide the speed, repeatability and stability
needed.
The prototype tunable filter is a precursor to mass production of low-cost, high-peformance
microwave
devices that meet the demanding requirements of future 5G networks.
These results were presented at the 2018 IEEE Wireless and Microwave Technology Conference (WAMICON) in a paper,
A 2.2 - 4.2 GHz Low-loss Tunable Bandpass Filter Based on Low Cost
Manufacturing of ABS Polymer, by Michael D. Sinanis et. al.
