A MMIC QPSK Modulator

Active and Passive Electronic Components, 2002
In this paper a MMIC QPSK modulator is described. The bit rate of the baseband signal is 155 Mbits/sec, while the frequency of the carrier is fLO=10 GHz . The modulation is performed directly at the RF band and therefore an IF stage is not necessary. The

Analysis and Design of a GaAs Monolithic Tunable Polyphase Filter in S/C Bands

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
This paper proposes a new topology of a 2-Stages Active Polyphase Filter (APPF) in MMIC GaAs technology. This new topology, named “radial”, allows a greater balancing of output signals phases and amplitudes, over the actual APPF’s at the state of the art.
