A 1.8-GHz low noise amplifier for wireless telecommunication systems, developed using the 180-nm CMOS technology, has been offered. An example of architecture of the narrow bandwidth high frequency low noise amplifier using the noise cancellation method has been considered. In order to improve the matching of the impedances at the input on the narrow band a narrow band matching circuit in the option with low quality factor on-chip inductors has been implemented. The developed amplifier provides the gain of 24 dB, the noise figure of 2.7 dB and the reflection coefficient S11 - 25 dB.

The main stages of creating the on-planet and orbital stations and the technical requirements to parameters of the robotic complexes communication network have been considered. Among the existing features of interaction of space systems, in addition to the capacity of the several Gb/s order, the requirement of adaptability, high robustness and reliability of the radio link can be distinguished. The comparative characteristics of phase modulation without phase break, of the phase four-position modulation with the shift of quadratures, array modulation with the application of the convolution code 4D-8PSK-TCM have been described. It has been shown that the parameters of the corresponding perspective electron-component base, which is based on GaN, permit to provide the power high density achieving 10 W/mm at the operating frequencies 30-40 GHz, for microwave power amplifiers, and the ADC implementation by 0.18 μm and 0.09 μm CMOS technologies allows achieving the speed of up to 3.5 Gsamples/s for software defined radio modem.
