Design of low noise amplifier using common gate current reused topology for wind profiling radar

TL;DR: In this paper, a single stage design of low noise amplifier (LNA) common gate (CG) current reused topology using pseudomorphic high electron mobility transistors (pHEMT) for wind profiling radar application at 1.3 GHz is presented.
Abstract: This paper presents single stage design of low noise amplifier(LNA) common gate(CG) current reused topology using pseudomorphic high electron mobility transistors(pHEMT) for wind profiling radar application at 1.3 GHz. Though CG current reused topology is not sufficient for achieving the desired parameter of LNA such as noise figure, input and output return losses and stability, so source degenerated inductor topology is also used along with the current used topology for achieving desired parameter. Low loss and low cost RT/ duroid RO4003C substrate is used. The single stage LNA results show that overall gain (S 21 ) of 22.149 dB and a noise figure of 0.364 dB. Input and output return losses are less than −10 dB and total power consumption is 180 mW. To perform the linearity, input intercept point (IIP3) and output intercept point (OIP3) is simulated as 31.01 dBm, 47.95 dBm respectively.

TL;DR: In this paper, a Ku-band LNA at 13– 16 GHz is designed with low NF, high gain, and low power consumption for space application and implemented with three-stage cascade source degeneration technique.
Abstract: In this paper, a Ku-band LNA at 13– 16 GHz is designed with low NF, high gain, and low power consumption for space application This paper presents high gain, too low noise figure, and low power consumption low noise amplifier (LNA). Simultaneously achieving high gain and low noise figure (NF), a popular source degeneration technique is used. Also for achieving high gain, this work is implemented with three-stage cascade source degeneration technique. The proposed work also aims to optimize the input, output and isolation losses. For achieving a low noise figure, InGaAs HEMT technology is used and Ku Band at 13–16 GHz LNA is designed for space application. Simulated results are NF of 1.008 and 0.719 dB and gain of 29.70 and 22.83 dB. The less than −12 dB is achieved for return losses of input and output. The Stability Factor and Mu1 are greater than 3 at desired 13–16 GHz. The amplifier biasing V ds , I ds is 2V and 10 mA respectively are chosen. The Keysight Technology Advanced Design System is used for simulating all parameters. The LNA consumes the power of 250 mW from the simulated values.

Abstract: This paper presents high gain and too low noise figure low noise amplifier (LNA). To achieve high gain and low noise figure (NF), resistive feedback in conjunction with source degeneration is used. Also, for achieving high gain, this work is implemented with cascading two stages and for achieving low noise figure, InGaAs HEMT technology is used and Ku Band at 14 GHz LNA is designed for space application. Simulated results are NF of 0.76 dB, and gain of 30.67 dB. The less than −14 dB is achieved for return losses of input and output. The Stability Factor and Mu1 is greater than 4 at desired 14 GHz.

TL;DR: In this paper, a 1.5 GHz low noise amplifier for a Global Positioning System (GPS) receiver has been implemented in a 0.6 /spl mu/m CMOS process.
Abstract: A 1.5 GHz low noise amplifier for a Global Positioning System (GPS) receiver has been implemented in a 0.6 /spl mu/m CMOS process. This amplifier provides a forward gain of 22 dB with a noise figure of only 3.5 dB while drawing 30 mW from a 1.5 V supply. To the authors' knowledge, this represents the lowest noise figure reported to date for a CMOS amplifier operating above 1 GHz.

TL;DR: An MST radar operating at 53 MHz with an average power aperture product of 7 × 108 W m2 has been established at Gadanki (13.5°N, 79.2°E), India as mentioned in this paper.
Abstract: An MST radar operating at 53 MHz with an average power aperture product of 7 × 108 W m2 has been established at Gadanki (13.5°N, 79.2°E), India. The radar development has been accomplished in two phases. In the first phase it was commissioned in ST mode using a partial system comprising one quarter (16 × 16)of the Yagi antenna array and 16 driver units of the transmitters providing an average power aperture product of 4.8 × 106 W m2. In this part we present the radar system description, including off-line data processing, and some sample high-resolution vector wind measurements made in ST mode operation.

TL;DR: The potential of the MST (mesosphere-stratosphere-troposphere) radar technique for obtaining detailed information on the middle atmosphere was examined in this article, where the authors examined the relatively large body of literature that has been written over the past few years and outline some aspects of a promising future.
Abstract: We examine the potential of the MST (mesosphere-stratosphere-troposphere) radar technique for obtaining detailed information on the middle atmosphere. This technique-which uses very sensitive coherent VHF and UHF radars-is capable of detecting signal returns arising from weak fluctuations in the atmospheric refractive index. With certain limitations the MST technique is capable of continually observing winds, waves, turbulence and atmospheric stability over the height range 1–100 km with good-to-excellent time and space resolution. We examine the relatively large body of literature that has been written over the past few years and outline some aspects of a promising future.

TL;DR: In this article, the authors survey recent developments in the use of both VHF and UHF Doppler radars for probing the clear atmosphere and present design considerations for new radar systems.
Abstract: In the past few years, sensitive Doppler radars have been used to probe the clear atmosphere from the boundary layer up to stratospheric altitudes. Routine Doppler radar observations are now attainable over a wide range of frequencies at virtually all altitudes in this height range. Although a number of these systems operate at UHF (300–3000 MHz), sensitive Doppler radars have recently been developed that operate at VHF (30–300 MHz). These new systems employ large, inexpensive antennas constructed of phased arrays of dipole elements. This paper surveys recent developments in the use of both VHF and UHF Doppler radars for probing the clear atmosphere and presents design considerations for new radar systems.

TL;DR: In this paper, a wideband common-gate (CG) LNA architecture was proposed to achieve broadband impedance matching, low noise, large gain, enhanced linearity, and wide bandwidth concurrently by employing an efficient and reliable dual negativefeedback.
Abstract: This paper presents a wideband common-gate (CG) LNA architecture that overcomes the fundamental tradeoff between power and noise match without compromising its stability. The proposed architecture can achieve the minimum noise figure (NF) over the previously reported feedback amplifiers in a CG configuration. The proposed architecture achieves broadband impedance matching, low noise, large gain, enhanced linearity, and wide bandwidth concurrently by employing an efficient and reliable dual negative-feedback. An amplifier prototype was realized in 0.18-μm CMOS, operates from 1.05 to 3.05 GHz, and dissipates 12.6 mW from 1.8-V supply while occupying a 0.073-mm2 active area. The LNA provides 16.9-dB maximum voltage gain, 2.57-dB minimum NF, better than - 10-dB input matching, and - 0.7-dBm minimum IIP3 across the entire bandwidth.
