Repeater Block X-band
This Repeater Block is Low-Noise Receiver Amplifier (LNA) which is used for amplifying of weak X-band signals.
Signal gain is carried out by two blocks of amplifiers and bandpass filters – amplifying lines. These amplifying lines are connected to the corresponding branches of ferrite circulators, as a result forming diplexers. Diplexers divide by frequency the received signals from both inputs. The first block of amplifiers and bandpass filters amplifies the signal with a center frequency of 7.839 GHz, and the second block – with a center frequency of 8.150 GHz. These amplifying lines with inputs / outputs are connected to the corresponding branches of the ferrite circulators. Circular inputs are connected to the strip / waveguide transitions of WR112 waveguides. Their flanges are the inputs / outputs of the Repeater Block.
There are strip / waveguide adaptors at the Repeater Block inputs / outputs, their waveguide flanges are used for connecting the low-noise amplifier module to the antennas. The voltage of the Reaper Block is supplied via PC4 type connector.
