Low PIM, High Power Attenuators for DAS Systems, Test Sets, Field Tests, and Lab Applications
RD Microwaves designs assembles, and tests all RF low PIM attenuators in New Jersey using high performance directional couplers with the main line terminated with the highest quality low PIM cable. The directional coupler coupled port provides the actual attenuation value for the best possible PIM, accuracy, temperature, and load insensitivity at medium to high power levels for our premium level high power attenuator products intended for precision high power, low PIM amplifier test sets.
DAS system type attenuators are also offered with low cost alternative attenuation design methods to most effectively fit the application.
Described below, are a wide range of attenuator types from a length of cable with predetermined insertion loss at specified frequencies to individual and rack mounted multichannel assemblies.
All units are 100% tested for PIM , return loss, and accuracy over the specified frequency range.
Reflective and forward/thru PIM measurements are available in frequency ranges between 700 and 2600 MHz. High power verification testing and thermal testing is performed as needed.
