TCW1-33+

Product Overview

For RF paths operating from 2.3 GHz to 3.0 GHz, TCW1-33+ supplies transformer isolation and 1:1 impedance conversion. The unity ratio preserves the nominal 50 Ω / 50 Ω port relationship while converting between single-ended and balanced circuitry. Confirmed selection data includes insertion loss of 1.6 dB maximum, return loss of 13.93 dB minimum, phase balance of 3°.

The 0603 LTCC format supports short, symmetrical routing in cellular, WLAN and broadband microwave modules. At this package size, the recommended land pattern and equal-length balanced traces are required to preserve the published RF behavior.

Quality & Sourcing

Antrex Electronics can support sourcing of TCW1-33+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance ratio, package style and winding configuration. Alternative approval should be based on the confirmed electrical limits and PCB footprint rather than on a similar family name.
