In this paper we present the RF characterization of Gallium Arsenide heterojunction bipolar transistor (GaAs HBT) transistors under load mismatched conditions. The mismatch test is carried out on an real-time active load-pull system with load mismatch of voltage standing-wave ratio (VSWR) of 10: 1. It is found that the 1-dB compressed RF output power (1 dB), transducer gain (GT), and power-added efficiency differ by 5 dBm,6dB, and 15%, respectively, between the optimal and worst phase conditions.

The results show that the algorithm can sort out conventional radars and staggered PRT radars, and greatly increase the operation rate to meet the real-time requirements.

The performance of proposed model is better than the DI model and can compare with the dual-input canonical piecewise-linear (DI-CPWL) model.

This balun takes full advantage of the frequency-independent out-of-phase property of the odd TE0.5,0mode of the coupled-HMSIW system. As a result, a phase difference of 180° and balanced amplitudes between two balun outputs are obtained inherently over a wide frequency range. Thanks to the similarity of partial transverse fields, this odd mode can be excited by a conventional slotline in a straightforward manner. This design concept is verified by both simulation and measurement. Measurement shows that this balun has a fractional bandwidth of 97%, from 17 to 49 GHz, with a return loss of 10 dB at its unbalanced port; the in-band amplitude and phase imbalances between two balanced ports are within ±0.6 dB and ±5° (±10° at around 48 GHz), respectively.

Due to that the ground folds to the surface of substrate by loading metallic vias, pure horizontally polarized E-field is produced around the slot and a wide ARBW is obtained. Two degenerate modes in a single-fed patch antenna is slightly separated by the metallic vias, so a CP radiation is achieved. The proposed CP antenna exhibits a low-profile of 0.015 ‘λ.

Within a platoon, the lateral controller and the longitudinal controller are designed and implemented following the model predictive control (MPC) framework. The goal of the control algorithm is to reduce the tracking error, so we formulate the tracking control of the system as a nonlinear problem and solve it by the particle swarm optimization (PSO) algorithm.
