Tekbox TBRFC1 RF amplifier / current injector
Details
The Tekbox TBRFCI1 is a four-quadrant RF trans-conductance amplifier, current injector and current source for applications requiring controlled current drive over a wide frequency range. The output of the TBRFCI1 has no dead zone and is able to both source and sink current, making it suitable for dynamic load testing, component characterisation and current injection tasks.
With a frequency range of 0 to 50 MHz, the TBRFCI1 can deliver up to ±45 Vpeak and a maximum linear current of ±1 ARMS. It can be used as an RF power amplifier for driving Helmholtz coils or loop antennas, as a current injector for DC power supply testing, as an output amplifier for arbitrary waveform generators, or as a general-purpose dynamic load.
