Applications
RF Amplifier Biasing
ZFBT-282-1.5A+ can inject DC bias into the RF path of:
LNAs
RF amplifiers
Driver amplifiers
Other active RF modules
Its 1.5A current capability makes it suitable for devices requiring more current than standard PCB Bias Tees.
Active Antennas
The Bias Tee can supply DC power to an active antenna through the same coaxial cable carrying the RF signal.
This helps simplify installations where the antenna or RF front end is located away from the power source.
RF Test and Measurement
ZFBT-282-1.5A+ can be used as a laboratory accessory when a DUT requires simultaneous RF excitation and DC bias.
Typical equipment includes:
Signal generators
Spectrum analyzers
Network analyzers
RF amplifier test setups
Laser Diode and DC Bias Applications
Mini-Circuits also identifies laser diode biasing, DC return and DC blocking among the applications for this model.
