Aim
The aim of the present work was to investigate the overexpression of the wysR gene in Streptomyces albulus var. wuyiensis strain CK‐15 based on the ΔwysR3 mutant strain including the effect on morphological development, wuyiencin production and antibacterial activity. At the same time, we report a new rapid method for producing genetically engineered strains for industrial production of wuyiencin...
In this paper, we present a highly efficient compact size three stage distributed power amplifier (DPA) for high power broad bandwidth applications. The DPA is fabricated using InGaP/GaAs hetero-junction bipolar transistor (HBT) technology. The design trade-off between power, efficiency and terminal matching is discussed. Reactive termination is used at the idle port of input and output transmission...
