2m VHF antennas with high gain
- 2m SSB/CW-12.5 Ohm Yagis with extrem high gain and small bandwidth.
These Yagis were constructed as ultra-light, portable Yagis with extrem high gain. They have small bandwidth and are working from 144,0-144,8MHz with good SWR.
Base-Station RF Power-Amplifier Biasing
- Power amplifiers used in base stations require biasing for proper RF performance. This article explains the two classes of biasing that are prevalent in the RF industry, analyzes their characteristics, and shows implementations with existing ICs.
