Focus Microwaves’ RAPID digital tuner technology is now available for very wideband communication signals, supporting the latest 5G FR1 and IEEE 802.11ax standards. This new architecture leverages the raw performance of National Instruments PXIe-5841* PXI Vector
Signal Transceiver.
The Rapid VT, utilizes two PXIe-5841 VSTs to make a VNA architecture with up to 1GHz active load pull bandwidth capability. The system solution provides a flexible load pull test platform that can be used to test the latest high bandwidth and high modulation cellular
standards such as 1024QAM 802.11ax but can also be configured for fast load pull and s-parameter measurements. This opens up the possibility of using this system in all parts of the design cycle, from initial device characterisation, to MMIC or PA design, design verification testing and ultimately to product testing in the factory.

More Product Information



- Tiny “all-in-one” solution: no external control board needed
- Superior image quality: sub-micron lens movement with very low tilt. Now with higher dynamic stability
- Low voltage & power: 3.3 VDC input, zero power position hold
- Simple system integration: accepts high-level motion commands over standard serial interface (I2C or SPI)
- Flexible, production-ready system: compatible with M8 to M16 lenses and with typical image formats from 1/3” to 1/1.8”
- Lowest cost, fastest time to market: Fully-engineered “plug and play” solution

-
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!

The LN112-30 Lens Adaptor is used for creating a 30° focused beam spread when attached to a SL112 or SL162.


The SPARTE e100 is a hybrid antenna addressing the telemetry applications in S-Band, including hypersonic test articles.
The antenna is a combination of an Electronic Beam Steering supporting any elevation from -5° up to +95° and a single-axis mechanical rotation of the patch panel providing unlimited azimuth. The patch panel’s size enables the SPARTE e100 to achieve telemetry reception performance comparable to that of a 1.2m diameter dual-axis antenna.
This is achieved with a significantly simpler mechanical design, ensuring easier maintenance throughout the antenna’s operational lifespan.
The SPARTE e100’s rapid tracking capabilities, reaching speeds of up to 60°/s in azimuth and virtually infinite in elevation, make it an ideal “lock-on” antenna.

Focus Microwaves
Focus Microwaves is a pioneering engineering company, built around the innovations of its founder Dr. Christos Tsironis who developed his first manual tuner in 1973 and is the inventor of most existing electro-mechanical tuner families. The success of Focus is based on the engineering and manufacturing skills of its highly motivated and experienced team of engineers and technicians, who have been trained and encouraged to develop new technologies. In addition, listening to our customers needs and insights helps us discover and develop new and measurement methods on an ongoing basis, relentlessly pushing the limits of what is possible.
From humble beginnings in 1988, Focus has become the main supplier of advanced Load Pull and Noise Tuner Systems. Our mission is to provide effective, reliable and innovative solutions for non-50 Ohm testing (Noise and Load Pull) of RF microwave transistors, thus enabling our customers to compete in the marketplace with better designs and to advance the understanding and knowledge of the field.
