A layer-encoded interactive evolutionary algorithm (IEA) for optimization of design parameters of a monolithic microwave integrated circuit (MMIC) low noise amplifier is presented. The IEA comprises a combination of the genetic algorithm (GA) and the particle swarm optimization (PSO) technique. The ...
3.2.4 MMIC LNA module An extremely low-noise, high-linearity, high-power amplifier can be realized using a combination of a 0.5 μm GaAs e-pHEMT process, a few miniature surface-mount discrete components and an encapsulated chip-on-board package [8]. External 3 dB hybrid couplers enable th...
Each band, extending over one octave only, is then accommodated by a low-noise amplifier, to maximize the sensitivity of the system, and after amplification each band is further processed separately. In one realization of an ESM system, banks of contiguous filters are used to examine the ...
The HMC1131 is a gallium arsenide (GaAs), pHEMT, monolithic microwave integrated circuit (MMIC), medium power amplifier. It operates from 24 GHz to 35 GHz. The 4‑stage design typically provides a 22 dB gain, 23 dBm output power for 1 dB compression (P1dB), and 27 dBm saturated ...
