On Wafer RF/mmWave Load Pull

As recent wireless bands like 5G are being deployed and new ones are being defined such as Wi-Fi 6 ( or 802.11ax) more is being expected from the measurement systems: Broader frequency coverage, better tuning range, and uncompromised harmonic capability. Focus Microwaves introduces yet another industry first with its Low Frequency Delta Tuners (LFD) that start as low as 1.8GHz and cover up to 40GHz. Designers and test engineers now need to cover broader frequency ranges with the same device technology. Leveraging the industry unique DELTA tuner technology, the LFD tuners can connect directly to the probe, making them ideal for on wafer measurements. This direct probe connection is key in minimizing any loss between the tuner and the device under test, not only for fundamental tuning but also for high VSWR harmonic tuning required for high efficiency designs.

Idea for 5G measurements

The new M3620 offers great tuning range for both RF and mmWave bands. This model provides high VSWR fundamental tuning as well as three frequency tuning for sub 6GHz applications; its wideband probes also cover up to 40GHz making it very useful for engineers wanting to cover both FR1 and FR2 bands.
