In this paper, a novel linear polarized cavity-backed antenna based on normal InP HBT technology is proposed and simulated. In this design, half-mode substrate integrated waveguide (HMSIW) technique is used to create a radiating aperture, which helps minify the InP substrate and reduce the cost. The proposed antenna is numerically investigated using HFSS. The simulated results show that the proposed...
LTE-Advanced uses carrier aggregation (CA) of multiple component carriers (CCs) to achieve high-bandwidth transmission. To fulfill such technology, the novel carrier-aggregated modulator structure is proposed. In this work, the carrier-aggregated modulator is implemented in 0.18 µm CMOS technology and tested with two 10 MHz LTE-Advanced Release 10 signals to demonstrate the feasibility of the proposed...
A 2.4 GHz active quasi-circulator is implemented in TSMC CMOS technology. We propose a new architecture using current-reuse and adjustable signal cancellation to achieve a low-power, high-isolation and small-size circulator. The measured isolation from transmitter to receiver, , can be as high as 68 dB, which to our knowledge is the highest value ever reported...
A 2-6GHz broadband low-noise amplifier (LNA) with current reuse and noise-shaping technique is proposed for wideband matching, high power gain and flat noise figure (NF) response. The proposed UWB LNA is implemented in TSMC 0.18um CMOS technology. Measured results show that power gain is greater than 15dB and input return loss is larger than 10dB from 2 to 6GHz. The input third-order intercept point...
