TCW1-133+

Overview

The TCW1-133+ is a ceramic RF balun transformer from Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of 8 GHz to 13 GHz with a 1:1 impedance ratio and 50 Ohm nominal impedance. The component features an insertion loss between 1.7 dB and 2.5 dB, amplitude balance of 1.7 dB, and phase balance of 13 degrees. It is housed in a compact 6-SMD, no-lead package measuring 1.6 mm x 0.79 mm x 0.61 mm, suitable for board mounting.

Feature Summary

• Provides balanced-to-unbalanced signal conversion in the 8-13 GHz microwave range
• Utilizes LTCC technology for a compact, robust surface-mount footprint
• Maintains stable electrical performance across wide bandwidths

Applications

• Wireless communication systems operating in UWB bands
• RF front-end modules requiring signal balancing
• Test and measurement equipment for high-frequency analysis

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Mini-Circuits or authorized distributors before integration. Confirm that the 6-SMD package dimensions align with your PCB layout constraints. Ensure that the operating temperature range of -55°C to +125°C meets your environmental requirements. Cross-reference the part number suffixes to ensure exact functional equivalence.

Selection Notes

Select this component when a 1:1 impedance transformation is required at frequencies above 8 GHz. It is suitable for designs prioritizing small form factors due to its tiny ceramic construction. Consider the insertion loss and phase balance specifications against system sensitivity requirements. This balun is appropriate for applications where standard wire-wound transformers are too large or lack sufficient high-frequency performance.

Part Context

The TCW1 series represents Mini-Circuits' line of tiny ceramic RF baluns covering 700 MHz to 6 GHz, though the TCW1-133+ specifically targets the higher 8-13 GHz segment. These components are part of a broader portfolio of passive RF devices including filters and amplifiers. The TCW1 series is known for providing reliable signal conditioning in compact packages for modern wireless infrastructure.
