Introduction

GMPDST (Guided Mode Purification and Distribution System) is one of the RF Accessories that has great value in modern RF industry. To begin with, the introduction of GMPDST application field and working principle are worth to mention, as it is an important component in the receiver cold signal path. It can work as a noise filter, in-line amplifier, band-pass filter, or a frequency mixer, depending on the need and its related applications.

Application Field

GMPDST is mainly applied in the military, although its components like angle tuning, in-line amplifier, and equalizers can be found in the consumer market as well. In the military, the main purpose for using GMPDST is to clean up incoming signals and convert them for different frequencies or uses. It can be used for transmitters, receivers, signal multiplexers, and even in networks of connected equipment. There are different types of GMPDST available for different application needs, such as differential and single-ended GMPDST, as well as waveguide, coaxial, and microstrip GMPDST.

Working Principle

The actual working principle of GMPDST differs depending on the type and application. However, the two primary components of the system are the amplifier and the angle tuning unit. The amplifier is responsible for amplifying, or increasing the power of, the incoming signal. This can be done either through the use of an active device (transistor) or a passive device (inductor or capacitor). The amplifier also serves to filter out any unwanted signals or noise as well. The angle tuning unit, or resonator, is responsible for converting the input signal to a different frequency, or tuning its frequency. This can be done either by the use of an inductor-capacitor (LC) tank circuit, or a varactor diode. This frequency conversion allows the GMPDST to function as a signal mixer or frequency converter.

Conclusion

In conclusion, GMPDST is a valuable component of the RF industry, especially in the military. It can serve as both a noise filter, amplifier, and even a frequency mixer, depending on the need. The two primary components of the system are the amplifier and the angle tuning unit, and the actual working principle depends on the type of GMPDST and its related application. Regardless of the end-use, GMPDST has proven to be a practical solution for clean signal reception and frequency conversion.
