The Design of a Thermally Efficient 1:256 Ku-Band Feed Network for a MMIC (Monolithic Microwave Integrated Circuit) Phased Array

Abstract

A thin, thermally transparent, 1:256 corporate feed network for use in a GaAs MMIC Ku-Band phased array antenna has been designed. The network will be realized using a recently developed RF transmission medium called CHANNELINE. CHANNELINE consists of a core of TFE coated copper wire placed in a channel routed through a heat exchanging metal structure which composes the backside of the array. This unique packaging arrangement conserves both volume and weight while simultaneously allowing the rapid transfer of internally generated heat. The network is comprised of a 1:4 waveguide to CHANNELINE divider, four 1:16 microstrp/CHANNELINE dividers, and sixtyy-four 1:4 microstrip dividers. The final 1:4 divider is colocated in the module with the GaAs MMIC elements. This network is expected to realize better than 15 dB of return loss with less than 1:3 dB insertion loss over an 8% bandwidth. Finally, the current status of array hardware is presented.
