A Doherty power amplifier at band 2.11-2.17GHz is simulated with the MRF8S21120H transistor. The P1dB is above 52dBm, and its efficiency is above 41% in 6dB back-off region. It demonstrates an efficiency improvement of 12.1% at 6dB back-off point. And the upper IMD3 is -36.4dBc, ...
Essential to the functionality of qubit-based sensors are control protocols, which shape their response in frequency space. However, in common control routines out-of-band spectral leakage complicates interpretation of the sensor’s signal. In this work, we leverage discrete prolate spheroidal sequence...

The amplifier circuit implements a differential telescopic cascode pair using p-type JFETs. It has figure of merits involving low bias current, low offset voltage and current, and high CMRR. The common-collector common-emitter(CC-CE) configuration is used as the load for the input stage ...
Simulate changing array impedance as a function of beam angle to study the impact of impedance mismatch and gain compression on front-end amplifier performance Defining Phased Array Configurations Specifications for any phased array radar are driven by the platform requirem...
The simplest case of the inverting amplifier, where it is common practice to bypass the feedback resistor, serves to illustrate the inverting relationship (Figure 3). Bypassing the feedback resistor is intended to limit noise bandwidth, and it does indeed remove noise presented as an input ...
