These coaxial attenuators cover a broad frequency range of dc to 50 GHz and provide tightly controlled, fixed attenuation values of 3, 6, 10, or 20 dB with low VSWR.
With several millimeter-wave frequency bands currently under investigation for 5G, an innovative dual-band power amplifier has been designed that addresses two of the proposed bands using a single component.
The brands that Infinite is buying include Kaelus, Polyphaser, Transtector Systems, and RadioWaves. The company is paying a little more than their total revenue last year.
This novel asymmetric Doherty amplifier design uses multiple GaN HEMT devices to achieve 1 kW output power with 65% average efficiency for cellular transmitters from 2.11 to 2.17 GHz.
Wearable antennas will play a large part in achieving improved wireless connectivity on 5G communications networks.
Vacuum-tube electronic devices provide the highest energy of available signal sources at terahertz frequencies.
