In this paper we propose a parallel two-finger unit transistor MMIC low-noise amplifier design technique which enables the design of wideband and high linearity low-noise amplifiers with very stable, predictable
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 ...
11.2.1 Noise in a Microwave System In a microwave system, a small signal can be measured even when no applied signal is present. This is due to noise that can come from several sources. The sensitivity of receiver components, such as the low noise amplifier (LNA) and mixer, is fundamenta...
, a controllable integrated attenuator 122, a controllable integrated transmit/receive switch 124, a relatively high power integrated amplifier 126 on the transmit leg of the MMIC with an integrated transmit/receive limiter 128 and integrated low noise amplifier 130 in the receive leg of the MMIC....

The 2 to 6 GHz, 10 Block GaAs MMIC Amplifier: An Overall Design for a Low Cost Commercial Product In order to address the 2 to 6 GHz GaAs MMIC amplifier needs of the largest possible range of commercial and industrial applications, a definition calle...
Keywords: LNA; current reuse; gain adjustable; noise 1. Introduction The low noise amplifier (LNA) is one of the important components in the front end of the radar receiver, and its noise figure directly affects the sensitivity of the receiver. At the same time, it is hoped that it has ...
CD are the load capacitors, RD are the load resistors, and I0 is the tail current that biases both the differential amplifier and the latch branch. The clock CLK splits the circuit operation into two phases: amplification and latching. In the amplification (latching) phase, the CLK is ...
