The Mini-Circuits TCW4-262+ is a ceramic RF balun transformer with a 1:4 impedance ratio, designed for wireless communication applications between 2300 and 2600 MHz. It features a 0603 package measuring 1.60 x 0.79 x 0.61 mm, supports up to 2W RF power input, and provides DC isolation between input and output. The device exhibits insertion loss up to 1.7 dB, amplitude unbalance up to 1 dB, and phase unbalance up to 13 degrees relative to 180° over its frequency range. Constructed using LTCC technology, it operates reliably from -55°C to 125°C and is aqueous washable.
Mini-Circuits’ TCW4-262+ is a tiny ceramic RF balun transformer with an impedance ratio of 1:4, covering a variety of wireless communications applications from 2300 to 2600 MHz. This model provides low insertion loss, low phase unbalance (relative to 180°), low amplitude unbalance, and RF input power handling up to 2W. It provides DC isolation from input to output allowing it to be used for DC biasing of external circuits at the output. Fabricated using LTCC technology, the unit comes housed in a tiny, rugged ceramic package (0.06 x 0.03 x 0.02”) suitable for harsh operating environments.
