Abstract: An antenna based on the resonance phenomena of a fast-wave leaky mode is small in size, can be installed in a printed circuit board by using surface mounting technology, and can use dielectric materials with a relative permittivity of between 2 and 5.

Abstract: An RF receiver apparatus that is suitable for implementation as a monolithic IC core with minimum external components is disclosed. The receiver apparatus features low noise figure, low intermodulation and almost fixed input impedance over a broad frequency band covering cable TV, broadcast TV, direct broadcast satellite TV. Other outstanding features includes 40 dB dynamic gain controllable range and minimum electromagnetic radiation due to fully differential signal design. Above all, due to the highly integrated design of the invention, it is suitable for miniaturized tuner appliation.

Abstract: A dual-mode microwave/millimeter wave integrated circuit package with low cost, high operating frequency, quick cooling, and high reliability is disclosed. More particularly, the package structure of the invention supports both microstrip and coplanar waveguide operation modes, which cannot be accomplished by any prior microwave integrated circuit package structures.
