Spacewalker LNA 434 MHz

Spacewalker LNA 434 MHz is a new addition to Qorvo RF Accelerator that combats real-world satellite reception difficulties by receiving otherwise weak signals in areas with a lot of RF interference. In urban environments, it’s often difficult to receive PocketSat and CubeSat signals amidst strong DVB-T, TETRA, FM, and LTE signals from densely packed transmitter towers. The project was inspired by attempts to pick up signals from the MRC-100 pocket satellite. After many experiments and measurements, a novel low-noise amplifier circuit was devised to help city dwellers cut through the RF chatter.

Crowd Supply’s Helen Leigh spoke with Spacewalker LNA creator, Zoltan Doczi, a Senior RF Engineer at Decent Labs in a recent episode of The Teardown Sessions.

LimeNET Micro 2.0

Lime Microsystems is back with LimeNET Micro 2.0, a modular radio platform that leverages the Raspberry Pi CM4 and LimeSDR XTRX for their respective computing and RF features. It’s an ideal tool for a wide range of wireless applications ranging from experimental deployments to real-world enterprise installations.
