High Frequency, High Current and Standard Designs – to 40 GHz – for Signal Processing Applications

TTE will introduce a new line of Bias Tees at IMS2015. The line includes three series:

  • BTHF – high frequency series for 10 MHz to 40 GHz
  • BTHC – high current series for 500 MHz to 4 GHz and current handling to 7 A DC
  • BTS – standard series for 10 MHz to 18 GHz

All three series provide very low insertion loss, minimal return loss, desirable VSWR characteristics and extremely flat gain response over the series-specific frequency ranges. The products are manufactured using high-quality components and processes to deliver superior broadband performance. A summary data table is provided below. RoHS-compliant parts are available upon request.

Please refer to series datasheets for the most up to date information in case any data has changed since the news release issued.

Summary Data Table for TTE Filters Bias Tees:

BTS*-11G 0.01 – 11 0.7 15 1.5 : 1 25 1000
BTS*-18G 0.01 – 18 0.7 15 1.5 : 1 25 500
BTHF*-27G 0.01 – 27.5 1.3 15 1.5 : 1 25 500
BTHF*-40G 0.01 – 40 2.5 12 1.7 : 1 25 250

*For RoHS compliant, insert “R” in place of asterisk. Example: BTHCR-4G

These new bias tee series are designed for use in biasing active antennas, amplifiers and laser diodes, and for DC blocking or return in broadband microwave, RF, data communication and ADC/DAC applications, including laboratory test systems.  Relevant markets include commercial, industrial, medical, military/defense and test & measurement.

All series have an operating temperature range of -55°C to +100°C and are matched to 50 Ohms and measured in a 50 Ohm test set-up. Most of the series are manufactured with SMA female connectors. Please contact TTE for other options & custom designs.
