English to Russian Tech/Engineering Electronics / Elect Eng ultra-compact microwave circulators

Добрый день!
Помогите, пожалуйста, перевести is exacerbated by в следующем контексте:

Microwave circulatorsand isolators are currently used in RF front-ends to protect devices from impedance mismatches. These devices are also integrated in full-duplex systems when a single antenna is used. However, these devices are mainly fabricated by hybrid technologies (insertion of ferrite pucks in a stripiine or microstrip structure) leading to high buikiness and cost. Furthermore, bulkiness is exacerbated by the need for permanent magnets to poiarize the ferrite pucks. Thus, mass production of low-cost compact circulators remains a hot topic and new ideas and technologies are needed to improve the integration of these devices.

Заранее спасибо!
