The TCM4-452X+ is a surface mount RF transformer with a 1:4 impedance ratio, designed for 50Ω systems operating from 20 to 4500 MHz. It features a DB1627 case measuring 4.06 × 3.81 × 4.06 mm, with a height of 1.65 mm. Insertion loss is specified at ≤3.0 dB over the full bandwidth, with amplitude unbalance ≤0.5 dB and phase unbalance ≤5°. The device supports 0.25 W RF power and operates from -40°C to 85°C. It includes grounded pins at locations 2 and 5, with no connection required at pin 1. The transformer is aqueous washable and suitable for PCS, cellular, and wideband push-pull amplifier applications.
