Abstract
A 10 × 21 × 1 mm^3^, very compact low temperature cofired ceramic (LTCC) system‐in‐package (SiP) transmitter module is presented for future wireless terminal applications. Five GaAs monolithic microwave integrated circuits (MMIC) chipsets including a power amplifier, driver amplifier, mixer, and two frequency multipliers are integrated into a LTCC multilayer circuit for the heterodyne transmitter. The fabricated transmitter module achieves an output of 13 dBm at a RF frequency of 62 GHz, an IF frequency of 2.4 GHz, and an local oscillator frequency of 59.6 GHz. The up‐conversion gain is 11 dB; while the local oscillator signal is suppressed below −20.6 dBc with the image rejection mixer, and the image and spurious signals are also suppressed below −29.6 dBc. © 2007 Wiley Periodicals, Inc.
