Focus Microwaves provides modular microstrip, high-power, and ultra-low-loss coaxial fixtures designed for load pull testing of packaged transistors. Equipped with TRL calibration standards, these fixtures support transistor packages from under 0.1” to 1” wide. Special features include decade-wide Klopfenstein transformers (Fmax:Fmin ~10:1), water- and air-cooling options, and on-substrate bias networks. Microstrip fixtures (PTJ-x*) offer 50Ω lines, λ/4 or taper transformers, harmonic traps, and DC bias networks, while Minimum Loss coaxial Test Fixtures (MLTF-x*) feature low insertion loss (< 0.03 dB at 2 GHz) with connectors including 7mm, N, and 7/16, spanning up to 18 GHz. Both types support water cooling for RF power up to several hundred Watts.

- Combine up to 16 SPDT or 8 multiport, high-performance relays in a 2U footprint
- Latching/Terminated options (EX7204L)
- LXI/LAN and USB command and control options
- Embedded web interface provides interactive utility to monitor and control relays from anywhere in the world
- Flexible API supports IVI and Linux development environments minimizing software investment
- LXI trigger event implementation provides seamless test synchronization with external devices
- Store up to 128 relay configurations for quick recall, including automatic power-up state

Focus Microwaves' bi-directional couplers, available in 40, 67, 110 and 120 GHz models, offer high directivity and low insertion loss. These couplers provide precise measurements, making them ideal for advanced RF and microwave testing, ensuring accuracy and efficiency in both R&D and production environments.
