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.

Noise measurements allow the determination of the four Noise Parameters of a device (transistor). There are four Noise Parameters which fully describe the noise behaviour of an active or passive device at a given frequency.
Focus Microwaves pushes the boundaries of tuner technology once again. While 6G frequencies and applications are still being defined, Focus took the initiative and developed a new family of waveguide tuners designed for frequencies greater than 110GHz. Leveraging the success and technology of the DELTA tuners (industry standard for direct connect on wafer applications) and combined it with the micro-metric accuracy and repeatability of the small footprint omega tuners. These new waveguide tuners will revolutionize the Sub-THz bands.

Focus recommends TRL Calibration Kits for applications such as load pull & noise parameters. Due to high reflection and low loss, tuner S-parameter measurements represent a challenge for VNA’s, because of error term determination and coupler directivity. Long experience has taught us not to rely on other calibration techniques than TRL (Thru-Reflect-Line). The popular SOLT technique is conditionally useable, but not guaranteed, up to 4GHz. The much convenient ECal method has provided questionable and inconsistent results. Our Customers are advised to be very careful with VNA calibrations, because the whole measured data depends on that.
Because of this, and to save our customers time and doubt, Focus has developed and offers a set of precise and reliable TRL calibration kits from 0.03 to 110 GHz with the following connector types: 7/16, N, APC-7, 3.5mm, 2.9mm, 2.4mm, 1.85mm, WR-15, WR-10. Our calibration kits are compatible with all commercial network analyzers.

Focus offers a complete range of manual tuners. The MMT series use the same RF technology and precision as a comparable automatic tuner.
They are available in octave and multi-octave bands between 400 MHz and 18 GHz and provide high VSWR at DUT reference plane with a high reliability.
For harmonic tuning requirements, the MMT series can be enhanced, referring to as option –H2 and –H23, using a similar concept as Focus’ harmonic rejection tuners (PHT).

Focus provides the deepest portfolio of wideband fundamental and harmonic passive tuners. Passive impedance tuners generate controllable reflection factor (Impedance) across the smith chart over a given frequency range. Focus uses two basic technologies:
-
From 100MHz to 120GHz we use the slide screw technique in which a reflective probe is inserted into a low loss slotted transmission line.
-
For frequencies from 10MHz to 170MHz we use a lumped element technology, whereby variable capacitors are connected with optimized lengths of coaxial cable. To view our Low Frequency Tuners, Click Here!
Most Focus Passive Tuners use long lasting RF probes which are designed for optimal tuning accuracy and are free of spurious resonances. The combination of multiple probes provide ultra wideband coverage in one single tuner. All Focus Passive Tuners are LAN controlled and include on-board impedance synthesis firmware.
