MIC AND MMIC INTEGRATED RF HEADS

Summary

The development and design of the Ku‐band automatic tracking system are based on MIC, waveguide, and MMIC technologies. The power divider and combiners in the power amplifier module are waveguide power combiners to minimize losses in the transmitter. Packed MMIC components are used to minimize system volume and weight. The tracking monopulse system consists of antennas, low‐noise amplifier (LNA), phase comparator array, and a controller. The RF head goal is to receive and transmit X‐band RF signals via monopulse micro‐strip antenna. The RF signal is downconverted to 60 MHz. The RF head may be employed in combined electromagnetic and optical seekers. The development and design of the X‐band RF head are based on MIC and MMIC technology. The antenna array has four output ports: sum, azimuth difference, elevation difference, and guard. The antenna output is connected to the RF head input ports.
