Detailed Description for T4-6T-KK81+

Product Overview

T4-6T-KK81+ combines a 1:4 impedance ratio with a 20 kHz to 250 MHz bandwidth in Mini-Circuits’ KK81 package. It supports both balun operation and impedance transformation across low-frequency, IF, HF and VHF signal chains.

The wide span means performance varies with frequency, so the manufacturer’s typical curves are more useful than a single nominal loss figure when selecting it for a narrow operating band. The KK81 suffix identifies the mechanical version and should be matched to the PCB land pattern in qualified equipment.

Key Features

  • Manufacturer: Mini-Circuits
  • Part Number: T4-6T-KK81+
  • Product Category: RF Balun / RF Transformer
  • Device Type: KK81-packaged wideband 1:4 RF transformer

  • System / Port Impedance: 50 Ω
  • Impedance Ratio: 1:4
  • Package / Case: KK81, approximately 0.58 × 0.30 × 0.26 in
  • Mounting Type: Surface mount

Applications

  • Wideband IF and HF/VHF impedance matching
  • Balanced amplifier and mixer coupling
  • KK81-based production and repair requirements

Quality & Sourcing

Antrex Electronics can assist with sourcing T4-6T-KK81+ for legacy and current RF assemblies. Transformer substitutions should match the winding ratio, operating band, power/current limits, pin configuration and package footprint.
