In this paper, the design and implementation of microwave integrated ultra-low-noise amplifier (LNA) is proposed. The LNA is designed at ISM-band, 2.45 GHz. With a gain of 7.87 dB and an NF of 0.893 dB, the LNA has a power consumption of 62 mW at 3.5-V supply voltage. The LNA has the larger gain with 40 MHz bandwidth. The input and output return losses of the LNA are −10.404 dB and −22.371 dB respectively...
In this paper, we present a formulation for extracting the noise wave correlation matrix of a linear two-port device-under-test (DUT) from measured noise powers using a designed six-port network. The noise powers are measured using a conventional noise figure analyzer. The extracted noise wave correlation matrix can then be converted into conventional two-port noise parameters. The proposed measurement...
This paper presents a high gain, low noise Cascoded LNA using T-matching network applicable for wireless applications. The amplifier use FHX76LP Low Noise SuperHEMT FET. The LNA designed used T-matching network consisting of lump reactive element at the input and the output terminal. The cascode low noise amplifier (LNA) produced gain of 18.5 dB and noise figure (NF) of 1.30 dB. The input reflection...
This paper presents the design and fabrication of radio frequency amplifier (RFA), which operates at 5.8 GHz unlicensed frequency for WiMAX application. The RFA designed used T-matching network consisting of lump reactive elements, 3 dB attenuator and microstrip line at the input and output impedance. The RFA developed in this project contribute a gain of 15.6 dB with overall noise figure of 2.4 dB...
