FormFactor - Cascade Eye-Pass Probe - Durable multi-contact wafer probe with controlled impedance power bypass technology
- High performance power bypassing provides low-impedance and resonant-free connections to 20 GHz
- RF bandwidth to 500 MHz
- Long probe life: > 250,000 contacts
- Beryllium-copper tips for gold pads or tungsten for aluminum pads
- Oscillation-free testing of wide-bandwidth analog circuits
- Use with ACP series probes to provide functional at-speed testing for known-good-die
- Mix multiple contact types: Ground, Power (Standard or Eye-Pass), Logic/Signal
- Low and repeatable contact resistance on aluminum pads ( < 0.25 Ω on Al, < 0.01 Ω on Au)
The multi-contact Eye-Pass probe provides controlled impedance power connections enabling functional testing of even the most challenging circuits on-wafer. The high-durability composite multi-finger tip provides high compliance and ensures precise alignment. This custom probe allows the user to select the footprint pattern best suited for the application, with up to 12 contacts per probe head. Available contact types are ground, logic, standard and Eye-Pass power supply, power supply sense, and ac signal.

Focus Microwaves' Harmonic Tuners are engineered to enable precise control of impedance at the fundamental and harmonic frequencies (typically f₀, 2f₀, and 3f₀), making them essential for nonlinear device characterization and power amplifier design.
These tuners feature multiple cascaded probes within a single tuner body, allowing independent or simultaneous tuning at multiple frequencies. Their robust design ensures high tuning accuracy, minimal insertion loss, and excellent repeatability across a broad frequency range. Harmonic tuners are the ideal solution for advanced Load Pull measurements where harmonic control is critical.

-
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)
-
Longest lifetime – typically one million (1,000,000) touchdowns
-
Ease of use – Less experienced operators can perform an RF calibration up to 500 GHz by simply pushing a button. This reduces the need of experienced users full time on each system.
-
Reduced Soak Time – The system will automatically re-align the probes to the pads if they drift from alignment. This reduces test time and increases throughput.
-
Unattended Use – Measurements can be left running over night or the weekend, testing all devices on the wafer, and at different temperatures without the need of an operator.
-
Calibration Monitor and Re-calibration – System will continuously monitor calibration drift, and automatically re-calibrate the system should the drift exceed a predefined limit.
