This article overviews the motivations and challenges for non-invasive wireless measurements of internal human body temperature. Microwave radiometry is an attractive method for internal thermometry, with the possibility of a wearable device that can continuously monitor temperature inside body tissues in different parts of the body, store the data...

This paper presents a study of near-field radiometry for internal temperature measurements of the human body. The radiometer has a Dicke architecture and operates in the 1.4-GHz quiet band for centimeter penetration into tissues with minimized radio frequency interference (RFI). The total blackbody power from a tissue stack is received by a probe p...

A systematic approach to CMOS Low Noise Amplifier design is presented. This approach uses an input impedance matching technique based on LC Ladder filters which will provide suitable input matching in any arbitrary band (S11<-10dB), also S22 is about -10dB in average. Using cascode structure, maximum power gain about 25dB is achievable. Noise level...

In this paper, the design and nonlinear analysis of a dual-band mm-wave Doherty power amplifier is presented. The Doherty power amplifier has been designed to operate simultaneously at 24GHz for ISM band and 28 GHz for LMDS applications with 1 GHz bandwidth at each band, using Large-signal model of 0.15μm GaAs PHEMT transistor with 6 dB of output p...

This paper presents the design and simulation of an envelope tracking power amplifier (ET-PA) for 28 GHz LMDS applications. A linearization algorithm is also employed in digital domain in order to reduce the distortion of the system. Simulation shows that proposed ET-PA delivers 19dBm output power with 21dB linear gain. Power added efficiency of th...

Millimeter-wave (mmw) technologies have made an intense interest in point-to-point radios, automotive radars, satellite services, and military circuits design. Recently millimeter-wave technologies are getting developed rapidly, and today, several technologies have been introduced in the market. This paper reviews the recent progress in mmw technol...

A high linear, high efficient base station power amplifier is presented. For increasing average efficiency in the highly modulated signal amplification, an envelope tracking technique is employed. Linearization is done using an adaptive digital pre-distortion (DPD). A passive five-port fabric is used in the feedback path instead of conventional dem...
