This high-performance bandpass duplexer is ideally suited to analog or digital PMR and trunking applications on congested communications sites. They feature a high RF input power rating, in addition to an excellent PIM and PIP rating for multiple carrier high power operation – particularly in digital protocols where peak-average modulation rations create high PIP values. Their design utilizes a milled block for high-performance and high reliability, and their small size offers convenient installation and efficient use of equipment rack space. A protective black epoxy finish assists environmental and corrosion protection.
