Humidity can alter the characteristic impedance of waveguides. Infiltration of humid air, snow, or rain into antenna feeder and waveguides can damage the front ends and deteriorate the performance of transceivers. This phenomenon is specifically critical for microwave systems that employ hollow waveguides, which include a wide range of systems such as broadcasting transmitters as well as radar systems. In these systems humidity increases the insertion loss as well as reducing the return loss. Therefore, due the high-power operation of these systems, the front-end modules are always at risk.
Sina Kavosh Electronic was established in 2000 by a team of experts, who has more than 30 years of experience in design, implementation, and maintenance of microwave networks. Sina Kavosh is the first and only Iranian company that is active in designing and manufacturing of dehydrators. The initial products of the company included dehydrators for microwave networks. Consequently, the skill of the design team assisted them in developing high capacity dehydrators, which are suitable for broadcasting transmitters (both FM and TV). These transmitters have more number of feeders with bigger sizes. Therefore, the advanced dehydrators provide high pressure dry air with multiple outputs. Over the recent years, the company has also served the national Iran Airport Company (IAC) with Airdryers for Airport Surveillance Radars (ASRs).
Sina Kavosh Electronic has several clients, including:
• Telecommunication Company of Iran
• Telecommunication Infrastructure Company of I.R.Iran
• Provincial telecommunication companies
• Islamic Republic of Iran Broadcasting (IRIB)
• National Iranian Oil Company
• National Iranian Gas Company
• IAC
