Impedance Transformer
Optimized for connecting 50-ohm antennas and pre-amps to the high impedance Red Pitaya inputs. It improves sensitivity and overall receives performance.
Less than 1 dB insertion loss from 2-50 MHz.
Compatible with STEMlab 125-10 and 125-14.
Description
The Red Pitaya 14:1 Impedance Transformer is optimized for connecting HF antennas to the STEMlab 125-10 and STEMlab 125-14 boards. Steps up 50-ohm antennas and pre-amps to the high impedance inputs. Improves sensitivity and performance. Less than 1 dB insertion loss from 2-50 MHz.
How to use
- Place a jumper across pins 2 and 5 of each input to bypass the internal attenuators, then connect the transformer:
Features
- Gold-plated male and female SMA connectors
- Shrink-wrap insulation
- Small and compact, room for one on each of the two antenna inputs
- Low insertion loss using a MiniCircuits® T14-1 wideband step-up RF transformer
One example of Improved Performance
-
- Using a passive antenna (VE3DO loop) with a Clifton Labs Z10042 11 dB Norton amplifier connected directly to a Red Pitaya at N6TV, strong intermodulation from two nearby FM broadcast stations on 92.3 and 106.5 MHz was clearly visible (106.5 – 92.3 = 14.2 MHz):
- Inserting the 14:1 transformer between the pre-amp and the Red Pitaya reduced the intermodulation significantly, and atmospheric band noise (wideband sensitivity) improved by about 4 dB:

Red Pitaya Wi-Fi Dongle
The WiFi dongle is compatible with STEMlab 125-10, STEMlab 125-14, SDRlab 122-16, and SIGNALlab 250-12. It is also compatible with the latest version of Red Pitaya’s official OS.
Note that the dongle will only enable your Red Pitaya unit to connect to other WiFi networks, and the ability to establish its own network/access point is not available yet.
It has improved connection stability and range, plus higher speed (40-50Mbits/s).
It comes with an RP-SMA detachable antenna, which allows you to extend it with a cable for better antenna positioning.
Caution: do not use the WiFi dongle without the antenna connected.
