Concern “Sozvezdie” Has Developed a Series of Transistors for 5G Communication Networks

JSC “NIIET”, part of JSC “Concern ”Sozvezdie“, developed the transistor PP9137Ŕ designed to create new communication systems of 5G and the quadcopters, it is included into the line of microwave GaN transistors.

Transistors have unique properties: a high value of specific output power, a wide matching band, a high value of the breakdown voltage of drain-source. They provide high performance of energy parameters such as output power (from 5 W to 50 W), power gain (from 9 to 13 dB), drain efficiency (at least 45% at the test frequency of 4 GHz and 2.9 GHz).

Prototypes of devices passed successful tests as components of the equipment at the enterprises-consumers. Starting from the second quarter of 2017, the line of transistors is supplied to more than 20 organizations for test operation in quadcopters, radio stations and in the location equipment of the airports.

It should be noted that the transistor PP9137A was presented at the stand of JSC “NIIET” at the XVII International specialized exhibition “Electronics and instrument-making”, held in St. Petersburg on November 21-23, 2017
