20 dB Isolation – 135 MHz to 175 MHz

Service Description

End Product + Design Documents + Production Documents

This high-power single-junction RF isolator is designed to operate within the 135 to 175 MHz frequency range. It supports continuous forward power handling up to 150 Watts and reverse power handling up to 100 Watts. The device features SMA female connectors on all ports and provides a minimum isolation of 20 dB, helping to protect sensitive components from reflected signals.

As a two-port passive component, the isolator allows RF energy to pass in one direction while significantly attenuating signals traveling in the reverse direction. Commonly used to shield equipment from the effects of load mismatches, these isolators help maintain system stability and prevent detuning of RF sources.

Built for reliability and high performance, this isolator offers low insertion loss and is well-suited for applications that demand consistent signal integrity and protection in high-power RF environments.
