The BT-100 is a wideband bias tee TX Power Amplifier (PA) that draws its current from the bladeRF 2.0 micro’s SMA connectors. The BT-100 is versatile PA that is an ideal intermediary or final stage amplifier in a TX chain. bladeRF-cli and the libbladeRF API can be used to enable and disable the bias-tee when it is needed. Care should be taken to avoid overdrawing current when powering the bladeRF 2.0 micro from USB bus power and enabling multiple bias-tee amplifiers simultaneously. In case the power budget (print hardware?in bladeRF-cli) is a concern, the bladeRF 2.0 micro can be powered by an external?DC power supply.

The BT-100 is backwards compatible with the bladeRF 1.0 and other transceivers. However, J3 must be populated?and FB1 may need to be removed?to prevent back-feeding DC voltage into ESD diodes and other sensitive circuitry that may exist and cause damage. Check the SDR’s schematic to determine the necessary precautions. Connect a +5VDC supply to J3.1 and ground to J3.2. Refer to the schematic for details.


NOTE: The BT-100 can only be plugged into the TX ports.

Frequently Asked Questions:

How can I tell if the PA is enabled?
A green light will appear on the BT-100 if the program or tool you are using enables the bias-tee. In addition to the command line commands listed above, add “biastee=tx” to gr-osmosdr sink blocks to enable BT-100 from within GNU Radio.

How many BT modules can be added to the bladeRF 2.0 micro?
All 4 ports of the bladeRF 2.0 micro are powered, so any and all RF ports can have a bias-tee module installed and powered.
