1.8-120GHz Tuners

Focus Microwaves' Delta tuners are at the cutting edge of RF and mmWave measurement technology. The 120GHz Delta tuners, developed with Keysight, enable harmonic tuning up to 3F0 for FR2 (24-39GHz) and have been crucial since 2019. High Frequency Delta tuners cover 2-50GHz, with unique models like the C5020B for noise parameter extraction, and the latest B series supporting ultra-wideband measurements from 5-67GHz. Low Frequency Delta tuners, available from 1.8-40GHz, provide high VSWR fundamental and harmonic tuning, ideal for both RF and sub-6GHz applications, with wideband probes covering up to 40GHz for FR1 and FR2 bands.
