This paper introduce design, implementation and measurement of front end crystal video receiver (CVR) that operates in the frequency range of 8–10 GHZ to intercept short duration pulse radar signals. The proposed receiver is designed with two outputs, video signal for real-time signal processing and an amplified version of the received signal for frequency measuring and/or determine the presence of...
In antenna arrays, the excitation amplitude of the individual elements is one of the major controls that can be used to shape the overall pattern of the antenna. In this paper, 1×10 rectangular patch antenna array is designed and simulated at 9.5 GHZ on specific microwave laminate using uniform, Dolph-Tchebyscheff and Binomial amplitude distributions for specific spacing between elements. The particular...
This paper demonstrates the design and simulation of input matching circuit for BLF578XR power transistor working at center frequency of 225 MHZ with bandwidth of more than 50 MHZ. Based on the calculated Q-factor and when using the transistor in push pull mode, the input matching circuit is designed in two stages, the first stage is a balun to match 50 ohm to 12.5 ohm and the other stage is to match...
In antenna arrays, power divider is used to divide the power between the elements of the array. Different power dividers have different characteristics based on its design. The aim of this paper is to design, simulate and analyze 1×2 rectangular patch antenna array working at 5.8 GHZ on specific microwave laminate for specific spacing between the elements. The particular spacing are 0.7λ, 0.8λ, 0...
The aim of this paper is to design, develop and simulate a linear patch antenna array working at 9.5 GHZ and integrate it on a microwave laminate. First, two rectangular patch antennas, one with a direct feed and the other with an inset feed are designed and compared to each other then 1×8 power divider is designed and simulated. Finally, eight rectangular radiating patches on a low dielectric constant...
