Abstract
This paper describes the design and fabrication of a 0.7‐mm‐thick compact Ka‐band low‐temperature co‐fired ceramic (LTCC) power‐amplifier module, integrating the 0.25‐μm PHEMT MMIC power‐amplifier design. The LTCC module, designed for a surface‐mounting structure, and composed of a five‐layer LTCC circuit with internal matching networks. The power‐amplifier module reveals 24‐dBm output power and 8‐dB power gain between 28 and 31 GHz, which is equivalent to less than 1 dB loss compared to the MMIC's performance. © 2003 Wiley Periodicals, Inc.
