Tagore is a fabless semiconductor company using GaN & CMOS processes. Tagore is headquartered in Arlington Heights Illinois USA and was founded in January 2011 by an experienced group of RF and power management design engineers. Tagore benefits from an executive management team with a valuable breadth of experience in the semiconductor industry. Tagore is a private company owned by the founders and by venture capital investors, and the employees.
RF Switch
High Power RF switches typically use PIN diode circuits. Switches using PIN diodes have several disadvantages. Pin diode switches require a large bias voltage to handle high RF power. These circuits also require a large bias current to reduce the ON resistance of the PIN diode. Generation of a large voltage from lower battery voltage requires a boost circuit with many active and passive components. GaN switches are the new high performance alternative.
Antenna tuning and filter tuning devices require very low resistances and high voltage handling capable RF switches. Low ON resistance is necessary to increase Q and minimize loss of tuning circuit. High Q tuning circuits can experience very large voltages even at low transmit power. Our solution is ideal for Antenna Tuning, and Filter Tuning.
