Additional Details

The UPG2214TK-E2 utilizes GaAs (Gallium Arsenide) technology, which provides superior performance at high frequencies compared to silicon-based switches. The switch is controlled by applying a voltage to the control pins, which switches the signal path between the input and output ports. It is typically used in 50-ohm impedance systems. The operating temperature range is usually specified from -40°C to +85°C. Proper impedance matching and PCB layout are critical for achieving optimal performance. The part is supplied in tape and reel packaging for automated assembly processes.
