SWR/PWR 픽업이 있는 1500W 로우 패스 필터

설명

Low Pass Filter With SWR/PWR coupler

This low pass filter directional coupler uses voltage doubler diode detectors to provide a DC voltage at the forward and reflected test ports. This coupler is ideally suited for VSWR protection circuits.

기술 사양:

– 86-110MHz 1500 watts maximum.
– 9차 체비쇼프 유형학.
– 초저손실 PTFE PCB; 엄격하게 제어되는 유전 상수.
– large #8 awg inductors.
– 0.12 dB insertion loss maximum; 0.1dB typical.
– -28dB return loss; -33dB typical.
– -47dB rejection at 176MHz. That’s the 1st harmonic of 88MHz
