Focus Microwaves - Bias Tee
Bias tees with a perfect balance of RF performance and DC power handling
Auriga’s Bias Tees balance impressive RF performance with heavy-duty power handling across multiple frequency bands ranging from 100 MHz to 67 GHz. They are designed for rigorous usage without sacrificing RF performance. Only the highest-quality materials are used to minimize signal loss and enable efficient heat removal.
These highest-power bias tees include a fast-acting fuse to protect DUTs against current spikes. A DC sense port is provided for accurately measuring the incident DC voltage. Models requiring external heat sinking include pre-tapped holes for easy mounting.
Auriga high power models are also often used in Wideband modulation applications, where attention is needed to properly terminate the impedances seen at the baseband frequencies.
Typical applications for Auriga bias tees are high power pulsed IV, pulsed load pull, wideband noise parameter extraction and pulsed s-parameter (used in compact modelling)
Focus is now introducing new 50 and 67GHz models for wideband noise and high power pulse applications. Leveraging decades of design work on high power bias-tees these new models offer great power handling for applications like 5G which also requires broad frequency coverage and very good baseband termination to allow for wideband signals operating at >20GHz.

More Product Information
Non-linear measurement data is often used to create a behavioral model for high frequency components. Formulations of these models have been defined in terms of traveling waves, with a desire to represent nonlinear behavior of high frequency transistors through a direct extension from linear s-parameters.
The Mesuro model portfolio is comprised of two variations of a behavioral model – each targeted at a particular end use – Cardiff Model Lite (CML), where the desired output is a local model, and Cardiff Model+ (CM+), which incorporates higher order mixing terms allowing a single model to fit over a range of impedance space.
