Ka- and W-band MMICs on microwave and millimeterwave device arrays (MMDA) using 0.1 μm T-gate PHEMT

Abstract

A variety of Ka-and W-Band MMICs have been developed on common sets of Microwave and Millimeter-wave Device Arrays (MMDA) using a 0.1 pm T-gate process. The MMDA approach, similar to digital gate array techniques, has the potential to reduce the cost and cycle time (CCT) of high performance MMIC insertions in low-to-medium volume systems. Various types of MMICs, designed on the same sets of MMDA, have a wide performance range; LO power of 18-19 dBm in Kaband, oscillator power of 16-18 dBm in Ka band, mixer conversion loss of 10-12 dB in Ka-and W-bands, doubler of 46 to 92 GHz with 9 dBm power at 92 GHz.

“…Publisher Item Identifier S 0018-9480(99)07176-8. the fabrication time and cost of millimeter-wave MMIC's for military systems, the microwave and millimeter-wave device arrays (MMDA's) approach based on the masterslice concept was proposed [6]. However, the MMIC's fabricated using this approach do not offer reduced circuit area because they use microstrip-type MMIC's.…”
