Lecture



Plate antenna amplifiers are designed to increase the signal level and compensate for losses in the transmission lines. Approximately the same design allows their use in various designs of broadband antennas. Such amplifiers are manufactured using SMD technology using the most advanced low-noise transistors, which are manufactured by leading foreign companies - ITT, Siemens, Philips, etc. Due to the fully automated multiple control plate amplifiers have good reliability, and due to the protective coating, they are resistant to atmospheric effects.

Currently, the largest assortment consists of plate-type amplifiers SWA, WS, RA, RAE, GPS, etc. They have different circuit solutions, which makes it possible to achieve the desired results in areas with different levels of the received signal by the simplest selection.

In areas with a relatively good received signal level, amplifiers with a single amplification stage (single stage) SWA-1, SWA-1 / LUX, PA-2, S & A-110 are usually used.

In areas with insufficient received signal, two-stage (two-stage) amplifiers WS-2, SWA-3, SWA-4 / LUX, SWA-5 (SWA-6), SWA-7, SWA-8, SWA-9, PA are used. 5, S & A-130, PA-9, S & A-140, PA-10, S & A-120, PAE-14, PAE-42, RAE-43, PAE-44, RAE-45, PAE-65, PAE-65TS, WA-031, WA-032, WA-041, WA-042, WA501S-1.

Below are the technical specifications and their schematic diagrams of the above amplifiers, as well as their appearance.

The voltage supply to the plate amplifiers is carried out by adapters that differ only in the design of the case. The main schematics of power supplies are shown on page 115.
