This work presents a dual-band high-gain metamaterial radome which can increase antenna gain. This radome operates at the WiMAX (3.5GHz) band and the WiFi (5.8GHz) band. The refractive index of this radome is designed to near zero. The radiation beamwidth of antenna becomes small and the antenna gain is increasing. The size of this radome is 90 mm × 90 mm. This radome improves antenna gain 2.6 dB...
This paper reports on the design and characterization of a low phase noise MEMS oscillator with ultra-low polarization voltage. An innovative oscillation circuitry is also proposed by a high gain-bandwidth, low-power TIVA (trans-impedance voltage amplifier) which is composed of two stages: the I-to-V stage and voltage gain stage. The TIVA is fabricated using 1P6M 0.18 μm CMOS technology and has been...
A new distributed amplifier (DA) topology is proposed. This topology is the combination of the conventional distributed amplifier (CDA) and the cascaded single-stage distributed amplifier (CSSDA), which makes wideband amplifier by considering the gain, noise figure and output power simultaneously. From the measurements, the DA has a small signal gain of 20.5 dB, a 3-dB bandwidth of 35 GHz, and a gain-bandwidth...
A fully integrated 24-GHz 22-dBm power amplifier was designed and fabricated in 0.18-µm CMOS technology. Optimized device size selection and resonance matching techniques are adopted in this single stage power amplifier design. High pass matching circuit is used to reduce output losses and maintain gain flatness. The measurement results shows a 22 dBm of saturation power and 20 dBm of output power...
