Low-power 60 GHz low-noise amplifier (LNA) with a 9.379 dB peak gain and a 4.500 dB minimum NF is demonstrated in a GaAs Based technology. The LNA is composed of three stage of cascaded common-source stages with inductive degeneration technique. The 1st stage of common-source given to the input stage for simultaneous noise and input matching. Also, the further stages is used for gain enhancement and...
The emerging trend in wireless communication devices have shaped the requirement of micro-devices having the inimitable capability of operating in the radio frequency (RF) range. RF MEMS switches have brought about a revolution in the volatile area of nanotechnology, due to its exceptional and extensive switching capability.

The primary engine, powered the ascent of electronics is miniaturization. Presently Transceiver uses advanced CMOS technology and further miniaturization in the CMOS transistor is leading to unavoidable power dissipation. In this paper, we propose a double gate (DG) MOSFET based 5 GHZ Transceiver with Cascode low noise amplifier. The proposed Cascode Low noise amplifier is to reduce the power, overall...
RADAR (Radio Wave Detection and Ranging) systems are widely used now days for detecting a target, obtaining its location along with direction and velocity of detected object. Most challenging part in RADAR system is to getting better accuracy in range estimation and also frequency jamming. In this paper, I have designed a radar system transmitter and receiver using direct sequence spread spectrum...
To compensate the nonlinearity introduced by power amplifier digital pre distortion plays a very significant role in linearization of saturation caused by PAPR of input signal however it cannot be compensated through linear DPD. As a result this Power amplifier has to operate with back off and this results in poor efficiency. In this paper it has been illustrated that reduced adjacent channel power...
