en.Wedoany.com Reported - Planar Monolithics Industries (PMI) has unveiled its first internally developed broadband phase shifter integrated circuit (IC) at the IMS 2026 exhibition, operating across a frequency range of 100 MHz to 40 GHz.

PMI is a supplier of RF and microwave components, with product lines including low-noise amplifiers, limiters, filters, solid-state switches, I/Q vector modulators, and successive detection log video amplifiers (SDLVAs), primarily serving commercial, aerospace, defense, and communications markets.

According to PMI's Alex Giordano, the direct reason for developing this in-house phase shifter IC is that an I/Q vector modulator chip used in its existing phase shifter products has been discontinued. To maintain product supply stability and continue meeting the performance specifications required by customers, PMI decided to move away from relying on third-party chips and instead independently design and develop its own integrated circuit. This new IC adopts an I/Q vector modulator architecture, supporting an operating frequency from 100 MHz to 40 GHz, providing precise phase control capabilities across a wide bandwidth for RF, microwave, and millimeter-wave systems.

Phase shifters are widely used in beamforming networks, phased array radars, satellite communications, electronic warfare systems, communication antennas, frequency conversion equipment, and test instruments. Currently, PMI's phase shifter product series encompasses both analog and digital designs, with a phase control range of 360 degrees, low insertion loss, and fast switching characteristics, operating at frequencies up to 40 GHz. By developing key ICs in-house, PMI has enhanced its design autonomy, performance control, and long-term supply assurance for the core components of its phase shifter product line.
