Focus Microwaves offers a range of high-performance pulsed modulators, including 1-channel and 2-channels models, designed for precise signal modulation. These modulators are ideal for RF and microwave applications requiring accurate and reliable pulsed signal generation.

Focus Microwaves’ RAPID DT, built on Keysight’s M5000 PXI modules, delivers fast, broadband load pull and S-parameter testing up to 18 GHz. It supports CW and pulsed signals across wide bandwidths, making it ideal for advanced standards like 4096QAM 802.11be.

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 This system can be used in all parts of the design cycle Initial device characterisation MMIC or PA design Design verification testing Product testing in the factory.

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.

Calibrating tuners for Network Analyzers presents challenges due to high reflections and low losses, affecting S-parameter measurements. At Focus Microwaves, we advocate for TRL (Thru-Reflect-Line) calibration as essential for precise results, unlike the less reliable SOLT and ECal methods. Our comprehensive TRL calibration kits cover 0.3 to 110 GHz and support connector types including 7/16, N, APC-7, 3.5mm, 2.9mm, 2.4mm, 1.9mm, WR-15, and WR-10. Compatible with all commercial network analyzers, these kits ensure reliability and accuracy, crucial for dependable VNA measurements.

Discover the frontier of tuner technology with Focus Microwaves' new waveguide tuners, designed for frequencies exceeding 110GHz. Combining the success of DELTA and omega tuners, these instruments promise to revolutionize Sub-THz bands, offering a high tuning range in a compact footprint. With extreme precision and low-loss RF probes, these tuners ensure optimal accuracy and repeatability, setting a new standard in on-wafer applications.
