Transmitter - / receiver module for actively phases array antenna

摘要

This invention relates to a transmit and receive module for active phased array antenna system based upon a combination of hybrid microwave integrated circuit (MIC) as well as monolithic microwave integrated circuit (MMIC) technology. The module comprises a signal transmit chain having switching means (03) for switching the module to transmittance mode. Means are provided for applying pulsed RF signal to the said module from array manifold. A phase shifter (01) is connected to a digital attenuator (02) and the output of the attenuator (02) is connected to a power amplifier (04). The amplified signals from amplifier (04) are conveyed to a duplexer means (05) connected to said power amplifier (04) and for routing back the received signal through a receiver protector (06) and low noise amplifier means (07). Electronic means are connected to a power conditioner for controlling the operation of the device.
