Abstract

The paper presents the results of the development of a microassembly of the IF module for frequency conversion units in the 3–16 GHz band of the RT-13 broadband receiving system. The principles of construction and operation of the main components of the microassembly, as well as its main parameters, are given. The microassembly developed is an upgraded version of the previous device that was used in the receiving system. Microassembly consists of an input switchable attenuator, a low-noise amplifier, an amplitude-frequency response corrector, a low-frequency filter, an output amplifier, a directional coupler, and a detector. The –3 dB bandwidth is 2 GHz, which is twice the operating range of the previous version (1 GHz). The gain is 26 dB with “zero” attenuation of the input attenuator, which has a range of tuning values from 0 to 31 dB in 1 dB increments. The upper limit of the linearity is 18 dBm for 1-dB compression level. The dynamic range of the main and the detector channels is at least 60 dB.
