The Big Deal
• Extremely Wideband
CASE STYLE: GU1414
• Very high DC current up to 200mA
• Very low insertion loss,<1dB
• Well matched, VSWR1.1:1
Product Overview
TCBT-14+ is the world’s smallest footprint wideband Bias-Tee measuring 3.8 mm x 3.8 mm which utilizes
a unique design to cover a frequency range of 10 MHz to 10 GHz without resonances that are typically
observed over such broad bands.
It is designed to handle 1W of RF power and 200 mA current and is
suitable for automated pick and place operation.
Key Features
Feature
Advantages
Extremely wideband:
Broad bandwidth enables biasing of wideband MMIC amplifiers or other active circuits starting
at extremely low frequencies through microwave bands.
10 MHz to 10 GHz
Able to support most Class-A MMIC amplifiers with a P1dB of up to 22 dBm need less than
200 mA.
DC Current, 200 mA
Low Insertion Loss:
0.2 dB typ. To 3 GHz
0.5 dB typ. to 5 GHz
1.0 dB typ. at 10 GHz
When used at the output of the amplifiers in a typical bias application; the low loss
of the
TCBT-14+ exhibits minimal impact on gain and over temperature improving reliability.
Excellent matching:
Excellent VSWR of TCBT minimizes interaction effects and resulting gain ripple.
Use of TCBT-14+ with Mini-Circuits MMIC amplifiers has shown performance improvements
over traditional L-C networks over the entire band.
1:1.1 over 0.1- 4 GHz
1.2:1 over entire band
