TTB16G11-900-4P

Overview

The TTB16G11-900-4P is an RF balun transformer manufactured by TDK Corporation, designed for surface-mount applications. It operates within a frequency range of 174MHz to 860MHz and provides impedance transformation between unbalanced and balanced ports of 50 Ohm and 200 Ohm, respectively. The component features a phase difference of 180° ± specified tolerance and exhibits a maximum insertion loss of 3.0dB. Packaged in an 8-SMD configuration, this device is currently classified as obsolete.

Feature Summary

• Provides balanced-to-unbalanced signal conversion with defined impedance matching
• Supports wideband operation across the 174MHz to 860MHz spectrum
• Utilizes surface-mount technology for compact circuit integration

Applications

• RF wireless communication systems requiring signal balancing
• Antenna interface circuits operating in VHF/UHF bands
• Balanced transmission line interfacing in consumer electronics

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors or secondary market suppliers. Ensure that any acquired units are genuine and have not been subject to environmental degradation due to age. Cross-reference part numbers carefully to confirm compatibility with existing designs before acquisition.

Selection Notes

Engineers selecting this component must account for its obsolete status when planning long-term production cycles. The specific impedance ratio of 50/200 Ohm and the 180-degree phase shift are critical parameters for circuit functionality. Designers should verify that the 8-SMD package dimensions fit the intended PCB layout and that the frequency range adequately covers the operational requirements of the target application.

Part Context

The TTB16G11-900-4P belongs to TDK's portfolio of RF components, specifically within the balun category. These devices are essential for maintaining signal integrity in radio frequency circuits by converting between single-ended and differential signals. The product represents a specialized solution for impedance matching in wireless communication hardware, though its current lifecycle status limits its use to maintenance or legacy system support.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers should consult TDK technical support or authorized distributors for potential end-of-life alternatives or compatible replacement series that meet the required electrical specifications.
