Designs & Manufactures Active Modules for Industrial Application Such As:

     • GaN Power Amplifiers

Power Gan transistors have high efficiency to create more backoff in power amplifiers, they also have less power consumption than the previous generation of transistors (Gallium Arsenide), which have the advantage of generating less heat in the amplifier section and improve the thermal index of the system.

• LNA

LNAs are amplifiers of very weak signals. These amplifiers are usually located very close to the receiving antenna so that the signal-to-noise ratio during signal processing is of the desired value. A power amplifier amplifies both signal and noise at the input, LNAs are designed to minimize this additional noise. According to the working frequency and the amount of gain, LNA can be designed.

• Power Amplifiers

The power amplifier module in the radio is actually responsible for increasing the output power level of the radio. Power amplifiers usually consist of different classes. In this module, we encounter three amplifier classes. The first two classes are used as drivers and the third class is used as the main class of power amplifiers. The power amplifier is MOSFET type transistors.

• Mixers

Frequency Mixer is a non-linear module that produces two new output frequencies from two input frequencies. Usually, the new frequencies are equal to the sum of the input frequencies or the difference between them. But in the design, other frequency components will also appear in the output of the mixer. Active mixers are mixers that use an amplifier to amplify their output. Compared to passive mixers, these mixers consume more power and have more output noise.

• Switches

In the 1+1 radio system, a switch is used to connect two ODUs to the antenna due to the low loss of the switch compared to the combiner. This module has two NTYPE connectors and a 4PIN power connector and a waveguide passage for direct connection to the antenna waveguide opening. Two NTYPE connectors are used to connect the RF radio to the MAIN side of the radio and the STBY side to the radio. This module is used to convert radio 0+1 to radio 1+1.

Designs & Manufactures Passive RF Components Such As:

• Microstrip Filters

Filters have always been an inseparable part of telecommunication circuits. Considering the important role of filters in telecommunication systems and the constant updating of these telecommunication elements, there is always a need for research to improve the important parameters of filters. Some of these parameters include the sharpness of the filter around the cutoff frequencies, the reduction of filter losses in the passband, the reduction of the size of the filters, their characteristic tolerance and stability against temperature and impact, ease of construction, and low final price.

 

• Transformers

The design of the waveguide transformer for transition from a frequency band to a higher or lower frequency is designed and built by adjusting the impedance. In the design of the waveguide transformer, small losses and its characteristic stability, as well as small dimensions, should be taken into account.

• Duplexer

Duplexer or two-way is one of the telecommunication elements that combines the TX and RX paths and places them in a specific frequency range. This function is also possible in the reverse direction. The duplexer used in this radio is a waveguide type. In this type of duplexer, a waveguide filter is installed on the rectangular waveguide in each direction. The two filters installed on this rectangular waveguide are Comb Line Filter type, and based on this, by installing cylindrical walls inside the waveguide and making a resonator, we get the characteristics of a filter (interpass).

• Combiners

Combiners designed to be used in radio links are used in Hot St.By mode and have three ports, one port to the antenna and two other ports to two ODU devices. The combiner can be symmetrical or asymmetrical, which The asymmetric mode is 1-6 dB and the symmetrical mode is designed according to the customer’s opinion.

• Adapters

The adapters manufactured by this company are designed and used to transfer the wave form from the Berrie waveform to the N or SMA mode. Their body material is aluminum or copper, which can be used industrially and laboratory after electroplating. The working frequency of the adapters manufactured by this company is in the range of 4GHZ to 38GHz.
