    A surface mountable planar narrow bandpass filter is proposed and demonstrated at V-band. The filter is constructed using an integrated waveguide in an alumina substrate employing a novel microstrip line to waveguide transition. The insertion loss per one transition is less than 0.1 dB over 43 to 73 GHz. A fabricated three-pole Chebyshev filter exhibits an insertion loss of 3 dB with a 3.3% bandwi... View full abstract»

    The behavior of a 5.2-GHz transmit antenna array in time division multiple acess operation is investigated, where the power amplifiers are only switched on during the data bursts. Using monolithically integrated power amplifiers, two thermal time-constants are found, associated with gain and phase changes that alter the antenna pattern. In this letter, the correlation of these changes between mult... View full abstract»

    Recently, the conformal finite-difference time-domain (CFDTD) method has emerged as an efficient FDTD method with a higher order accuracy than the conventional FDTD methods that are degraded by staircasing errors. The only obvious point to further improve on the CFDTD method is its requirement for a smaller time step increment due to the existence of small irregular cells near the boundary. In thi...

    A 25-GHz complementary metal oxide semiconductor (CMOS) cascaded single-stage distributed amplifier (CSSDA) using standard 0.18-μm CMOS technology is presented in this letter. It demonstrates the highest gain-bandwidth product (GBP) with smallest chip area reported for a fully-integrated CMOS wideband amplifier using a standard Si-based integrated circuit process. The chip size including t... View full abstract»

  • A novel frequency doubler using feedforward technique and defected ground structure

    Publication Year: 2004 , Page(s): 557 - 559

    A novel design of frequency doubler using feedforward technique and defected ground structure (DGS) is proposed. The feedforward loop in the proposed frequency doubler suppresses the fundamental component (fo), and the DGS diminishes the higher order harmonics such as third, fourth, and so on. Due to the combination of feedforward structure and DGS, only the doubled frequency component ... View full abstract»

    We report on the high-performance monolithically integrated RF switch based on metal-oxide-semiconductor III-N heterostructure field-effect transistors (MOSHFETs). The radio frequency (RF) switch microwave monolithic integrated circuit (MMIC) consists of three submicron-gate MOSHFETs connected into π-type configuration. In the 0-10 GHz frequency range, the insertion loss is less than 1dB and th... View full abstract»

    Behavioral modeling techniques provide a convenient and efficient means to predict system-level performance without the computational complexity of full circuit simulation or physics-level analysis of nonlinear systems, thereby significantly speeding up the analysis process. General Volterra series based models have been successfully applied for radio frequency (RF) power amplifier (PA) behavioral... View full abstract»

    We investigated stability and phase noise of V-band millimeter-wave generated by using a hybrid integrated reciprocating optical modulator consisting of a pair of fiber Bragg gratings and a LiNbO3 optical phase modulator. The amplitude fluctuation of generated millimeter-wave was less than 1% without using feedback stabilization technique. Phase noise of the millimeter-wave was -74.3 dB... View full abstract»

    A new type of a slot antenna in which a slot is formed in wound-type around a dielectric substrate is proposed. In comparison with a conventional meander slot antenna, the proposed antenna has a wider bandwidth and smaller size. The proposed antenna has been designed on a gallium arsenide (GaAs) substrate and fabricated by integrated circuit process for the integration of the antenna with active c... View full abstract»
