Focus Microwaves’ DELTA series of electro-mechanical tuners is designed specifically for high frequency on wafer measurements. The tuner’s low profile allows it to be placed within the wafer perimeter and allows for a direct connection between the probe tip and the tuner, eliminating all possible insertion loss between the DUT and the tuner. This revolutionary new tuner design enables the engineer to achieve optimum tuning range, with a tuner whose footprint and weight has been dramatically reduced.

Supports the latest 5G FR1 and IEEE 802.11ax standards up to 1GHz active load pull bandwidth capability Test the latest high bandwidth and high modulation cellular standards such as 1024QAM 802.11ax

Focus’ modular microstrip, high power and ultra low loss coaxial  RF Test Fixtures are designed mainly for load pull testing of packaged transistors. All Focus test fixtures come with TRL calibration standards and support most transistor packages sized from less than 0.1″ and up to 1″.

An impedance tuner is an apparatus, which generates controllable reflection factor (Impedance) over a certain frequency range. Focus uses two basic technologies:

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.

3 Measurement States; Quiescent (OFF-State), Non Quiescent (ON-State), and Pre-State The Pre State is a short high voltage state used to activate

An impedance tuner is an apparatus, which generates controllable reflection factor (Impedance) over a certain frequency range. Focus uses two basic technologies:

Best price per contact – typically over one million (1,000,000) touchdowns RF/Microwave signal is shielded and completely air isolated in the probe body Excellent performance in vacuum environments and temperatures as low as 4 K, or as high as 300°C

Replace costly and inflexible test fixtures with easy-to-use probe tips Long lifetime – typically over 1,000,000 contacts GS/SG footprint up to 4 GHz and GSG up to 20 GHz High-power RF test: up to 30 Watts

High power – 66 W at 2.4 GHz and 43 W at 5 GHz Extremely low insertion loss of ≤ 0.4 dB (typical) up to 40 GHz Excellent contact control and low contact resistance High performance on any pad material (Al or Au)
