Abstract :
A 60GHz-band transmitter system-in-package (SiP) has been developed for future wireless communications applications. GaAs MMIC chipsets including a power amplifier, a driver amplifier, a mixer, and multipliers have been integrated on a LTCC multi-layer circuit for the heterodyne transmitter. The size of the whole transmitter LTCC module is 10mm × 21mm × 1mm. With an IF frequency of 2.4GHz and a LO frequency of 58GHz, 60.4GHz output of 11dBm is achieved, and the total gain is 12 dB. The link test for a 60GHz wireless communication shows that the transmitter communicates well with the receiver without any signal distortion.
