“…Design challenges of this project are switch matrix selection and low noise amplifier (LNA) selection. The switch usied for transmitterreceiver separation should have high isolation , high power handling capability and low insertion loss [8]. For the selection of LNA, it should have high IP3 and low noise figure.…”

In this paper, design and development of a 2x2 MIMO RF front end is demonstrated. It has an RF board with commercial transceiver chips and operates at 2.4GHz. In the RF front end the transmitting and receiving paths are separated by using switches. These switches are controlled by transmitter and receiver switches. The signals are then recombined after amplification on both sides. Many advances in radio design and architecture are now allowing for rapid changes in the field of radio design. These changes allow reduction of size, cost, complexity and improve manufacturing by using digital components to replace unreliable and in-accurate analog components. For this to happen, many advances in semiconductor design and fabrication were required and have come to fruition over the last few years. Some of these advances include better integrated mixers, LNA, improved SAW filters, lower cost high performance ADCs and programmable digital tuners and filters.

“…Transformers are often used for millimeter wave wideband LNA stage matching, which is helpful to realize signal conversion from single end to differential and reduce chip area. 12 The transformer realizes the bandwidth expansion by constructing the interstage magnetic coupled resonator. 5,6,[13][14][15] The basic principle is shown in Figure 2, by adjusting…”

SummaryWideband low‐noise amplifiers (LNAs) are widely used in 5G and 6G communication systems. This paper first analyzes two common bandwidth extension technologies: the stagger tuning technique and the magnetically coupled resonators (MCR) technique. Then, a four‐stage LNA based on double‐tuned transformer combined with stagger tuning idea and MCR idea was proposed. In order to improve the broadband characteristics of the LNA, the loose coupling double‐tuned transformer is carefully designed. Compared with the traditional stagger tuning LNA, it has better broadband characteristics, lower element error sensitivity, and lower design complexity. This designs a gain bandwidth product of 1.48 T with a −3‐dB bandwidth in 9.11 GHz and the noise factor is lower than 3 dB, which covers more than 45% −3‐dB fractional bandwidth. The LNA consumes 37‐mW power with a 1.1‐V supply and occupies 1.22 × 0.4 mm2.

An ultra wide band (UWB) receiver front-end operates at the UWB frequency range, starting from 9 GHz-10.6 GHz is proposed in this paper. The proposed system consists of an off-chip microstrip antenna and CMOS differential low noise amplifier with a differential noise canceling (DNC) technique. The proposed antenna is trapezoidal dipole shaped with balun and printed on a low-cost FR4 substrate with dimensions 10 10 0.8 mm 3. The balun circuit integrated with the ground antenna to improve the antenna impedance matching. Full-wave EM solver HFSS (High Frequency Structure Simulator) is used for modeling the proposed antenna. The CMOS LNA is designed using UMC 0.13µm CMOS process, and exhibits a flat gain of 19dB, maximum noise figure of 2.9 dB, 1dB compression point-16dBm, 3rd order intercept point (IIP3)-10dBm, and DC power consumption of 2.8 mW at 1.2 V power supply. Applying the noise canceling stage, the NF is reduced by 50% to be 2.75 dB while the power consumption is increased to be 2.9mW.
