A microwave signal receiver comprising a printed circuit board, in particular a microstrip circuit board, comprising an input port adapted to be operatively connected to an antenna for receiving in input a microwave signal (s_rx) picked up by the antenna, wherein the microwave signal receiver comprises: - at least one power dissipator; - an electronically controllable switch adapted to receive in input the microwave signal (s_rx) and a first control signal (s_blk), wherein the electronically controllable switch comprises a first output port and wherein, based on the control signal, the electronically controllable switch is configured to assume a conduction state to supply the microwave signal (s_rx) to the first output port, and a protection state in which the electronically controllable switch is such as to send the microwave signal (s_rx) to the power dissipator; - at least one low-noise figure amplifier comprising an input port operatively connected to the first output port and further comprising an output port for supplying in output an amplified microwave signal (s_a); wherein: - the electronically controllable switch is an SPDT - Single Pole Double Throw - switch having a second output port operationally connected to the power dissipator and wherein in the protection state the electronically controllable switch is configured to make the microwave signal (s_rx) available to the second output port; - the power dissipator is a termination dissipator; characterized in that the microwave signal receiver further comprises an electronically controllable attenuator operatively interposed between the electronically controllable switch and the low-noise figure amplifier for attenuating the microwave signal (s_rx), and wherein the receiver is configured to control the attenuator so that the latter assumes a first state in which it has a relatively high attenuation, and a second state in which it has relatively low attenuation, and wherein the electronically controllable attenuator assumes the first state when the electronically controllable switch assumes the protection state. - at least one power dissipator; - an electronically controllable switch adapted to receive in input the microwave signal (s_rx) and a first control signal (s_blk), wherein the electronically controllable switch comprises a first output port and wherein, based on the control signal, the electronically controllable switch is configured to assume a conduction state to supply the microwave signal (s_rx) to the first output port, and a protection state in which the electronically controllable switch is such as to send the microwave signal (s_rx) to the power dissipator; - at least one low-noise figure amplifier comprising an input port operatively connected to the first output port and further comprising an output port for supplying in output an amplified microwave signal (s_a); - the electronically controllable switch is an SPDT - Single Pole Double Throw - switch having a second output port operationally connected to the power dissipator and wherein in the protection state the electronically controllable switch is configured to make the microwave signal (s_rx) available to the second output port; - the power dissipator is a termination dissipator; characterized in that the microwave signal receiver further comprises an electronically controllable attenuator operatively interposed between the electronically controllable switch and the low-noise figure amplifier for attenuating the microwave signal (s_rx), and wherein the receiver is configured to control the attenuator so that the latter assumes a first state in which it has a relatively high attenuation, and a second state in which it has relatively low attenuation, and wherein the electronically controllable attenuator assumes the first state when the electronically controllable switch assumes the protection state.
