Passive Intermodulation (PIM) occurs when multiple RF signals encounter defects in materials or workmanship in an RF path. These defects behave like a mixer causing noise to be generated at mathematical combinations of the original carrier frequencies. PIM interference that falls in the receive band of a wireless system elevates the noise floor resulting in high dropped call rates, call blocking, slow data transmission speeds and decreased system capacity.
Kaelus is the industry leader in Passive Intermodulation test solutions. Since 1996 Kaelus has supplied RF equipment manufacturers around the world with precision IEC compliant test equipment to perform this critical test. From initial product design through high-volume manufacturing, Kaelus offers a wide range of PIM test solutions that enable equipment manufacturers to quickly and confidently verify the performance of their products.
PIM은 여러 RF 신호가 경로의 오류, 부품의 재질 또는 제작 기술에 결함이 있을 때 발생합니다. 이러한 결함으로 발생되는 PIM 간섭은 잡음을 상승시켜 통화 품질의 저하, 통화 차단, 데이터 전송 속도의 저하, 시스템 용량 부하에 영향을 끼칩니다.
