Wide-band GaAs MMIC low-pass filters
, 1994 Very small, Wide-band and low loss GaAs MMIC Bessel-Thomson, Gaussian and dissipative low-pass filters are proposed as low signal distortion filtering elements suitable for inclusion into high-speed fiber optic receivers.

Ultra broadband low power MMIC amplifier [PDF]
, 2000 A low power two-stage InP HEMT MMIC amplifier has been developed. The amplifier utilizes 0.12 µm T-gate InP HEMTs with 225 µm gate periphery. This compact microstrip MMIC is only 1.5 mm 2 in size. It exhibits gain of 12.51 dB at 15 mW of dissipated power

III-Vs Review, 2005 DARPA perspectives are probably anxiously awaited by those having to make the grade and eagerly anticipated by observers as the ‘sine qua non’ for advanced compound devices. Mark Rosker's paper reported on completion of phase 1 of DARPA's wide bandgap initiative and lays down the ambitions and expectations of phases II and ...

Analysis and Design of a GaAs Monolithic Tunable Polyphase Filter in S/C Bands
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsThis 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.
