TPCG-183+

Overview

The TPCG-183+ is a miniature low temperature co-fired ceramic (LTCC) transmission line designed for surface mount applications. It operates as a DC to 18 GHz thru-line with a characteristic impedance of 50 Ohms. The component features an 0805 surface mount footprint, facilitating compact PCB integration. Typical electrical performance includes an insertion loss of 0.5 dB and a return loss of 10 dB across the specified frequency range. It supports operating temperatures from -55°C to +125°C.

Feature Summary

• Constructs a robust signal path using low temperature co-fired ceramic technology for high reliability.
• Provides a versatile placeholder function within RF circuit layouts to maintain impedance continuity.
• Utilizes a standard 0805 surface mount package for automated assembly compatibility.

Applications

• Ultra-wideband RF and microwave circuit interconnects
• Signal conditioning in high-frequency communication systems
• Impedance matching networks requiring precise 50 Ohm transmission lines

Procurement Notes

Verify the specific datasheet revision and mechanical drawings prior to final design implementation. Confirm that the 0805 footprint matches the intended PCB layout constraints. Ensure thermal management strategies align with the specified operating temperature range of -55°C to +125°C. Cross-reference the manufacturer's ordering codes for any available packaging variations such as cut tape or reel options.

Selection Notes

Select this component when a fixed-length, low-loss transmission line is required between DC and 18 GHz. The LTCC construction offers stability superior to standard substrates in harsh environments. Consider the 0805 size constraint against available board space. Evaluate the typical 0.5 dB insertion loss against system power budget requirements. This part serves primarily as a passive interconnect rather than an active filtering element.

Part Context

This device belongs to the Mini-Circuits TPCG series of LTCC transmission lines. These components are engineered to provide consistent electrical characteristics in high-frequency designs. The series utilizes proprietary ceramic processing to ensure durability and performance consistency across wide bandwidths.

Replacement Considerations

Direct substitutes include other Mini-Circuits LTCC thru-lines with compatible impedance and frequency ranges. Verify mechanical footprint compatibility before substitution. Check datasheets for equivalent insertion and return loss specifications to ensure signal integrity is maintained.

FAQ

Is the TPCG-183+ a filter or a transmission line?

It is a thru-line transmission line designed to pass signals from DC to 18 GHz with minimal attenuation, not a frequency-selective filter.

What is the typical return loss specification?

The typical return loss is 10 dB across the operational frequency range.
