TC1-1TX+ Description

Short technical summary and product information.

The Mini-Circuits TC1-1TX+ is a surface mount RF transformer designed for a wide frequency range of 0.4 MHz to 500 MHz. It offers a 1:1 impedance ratio and is rated for 50 Ohm systems.

 

Key electrical specifications include a maximum insertion loss of 3 dB across the 0.4-500 MHz band, with tighter loss figures at lower frequencies. Amplitude unbalance is typically 0.1 dB, and phase unbalance is typically 2 degrees within the 1 dB bandwidth. The transformer also exhibits good return loss, specified at a minimum of 6.9 dB.

 

This component is suitable for applications such as VHF/UHF receivers/transmitters and push-pull amplifiers. It is housed in a compact 6-SMD package with flat leads, designed for easy surface mounting. The operating temperature range is -40°C to 85°C.

 

Features include excellent amplitude and phase unbalance, good return loss, a plastic base with leads, and aqueous washability. The maximum RF power rating is 0.25W, and the maximum DC current is 30mA.
