TC1-1-13M-34+

Product Overview

TC1-1-13M-34+ is a unity-ratio RF transformer covering 47 MHz to 1.4 GHz. It converts a 50 Ω single-ended signal to a balanced path without intentional impedance multiplication, making it appropriate for differential RFIC inputs where phase symmetry and broadband matching are more important than a voltage step-up.

The published limits include 1.5 dB maximum insertion loss, at least 14.32 dB return loss and 3° phase unbalance. Those values provide a concrete basis for receiver gain and differential-balance budgets across VHF, UHF and lower L-band operation. The five-terminal surface-mount implementation also keeps the transformer close to a mixer, tuner or amplifier, reducing unmatched balanced trace length.

Quality & Sourcing

Antrex Electronics can help source TC1-1-13M-34+ for current production, maintenance and obsolete-component requirements. For substitution review, compare the operating band, impedance ratio, center tap where applicable, package style and PCB footprint; electrically related Mini-Circuits suffix variants are not always mechanically interchangeable.
