Space-grade RF, ready for your CubeSat
S-band and UHF antennas and a 4 W down-link amplifier — ECSS-built, 5G NTN n256, in a 1U footprint
EpowerX-Evolve brings flight-grade RF front-end hardware to Indian satellite builders. Antennas and power amplifiers for CubeSats and small satellites — designed to the 5G Non-Terrestrial Network (NTN) S-band standard, manufactured to ECSS guidelines, and delivered with an Interface Control Document, datasheet and Certificate of Conformity for every produced instance. From up-link and down-link antennas to a redundant down-link amplifier, the front end drops onto a single CubeSat face or a 0.2U slice.
Space-Grade & Non/Terrestrial RF Hardware
Every product developed by RAME is available to order through EpowerX-Evolve with full technical support.
SPACE GRADE * ANTENNA
Space Frade UHF Antenna
High-performance UHF antenna qualified for satellite and spacecraft applications. Minimal mass, maximal reliability in the orbital environment.
UHF Band – Space Qualified – Low Mass
SPACE GRADE * S-BAND ANTENNA
n256 Up-Link S-Band Antenna
Space-qualified patch antenna array for NTN satellite uplink chains, meeting 3GPP Release 17 NTN operational frequency requirements.
S-Band UL – n256 NR Band – NTN Ready
SPACE GRADE * S-BAND ANTENNA
n256 Down-Link S-Band Antenna
Space-qualified parabolic-reflector antenna optimized for high-efficiency downlink chains in LEO/MEO satellite payloads.
S-Band UL – n256 NR Band – LEO / MEO
HPA * Space Grade
4W n256 & SOS Down-Link S-Band HPA
Space-qualified 4W HPA covering n256 NTN downlink and emergency SOS frequencies. High linearity and radiation tolerance for CubeSat and gateway transmit chains.
UHF Band – Space Qualified – Low Mass
RF Filter * S-BAND
n256 Up-Link S-Band BPF
Precision BPF for the n256 S-band uplink. Steep stopband rejection protects receiver chains from interference and intermodulation products.
S-Band UL – BPF High – Rejection
RF Filter * S-BAND
n256 Down-Link S-Band BPF
Companion BPF for the n256 S-band downlink. Low insertion loss with high stopband rejection for clean downlink receive chains.
S-Band DL – BPF – Low Insertion Loss
Protocol Stack * IoT / NTN
3GPP Rel. 17 NTN-adapted NB-IoT Stack
Complete NB-IoT protocol stack adapted for 3GPP Release 17 NTN operation — handling extended timing advance, Doppler pre-compensation, and coverage enhancement for direct-to-satellite IoT
NB-IoT – 3GPP R17 – NTN Adapted
5G FR2 * MULTIPLEXER
5G FR2 TN & NTN Multiplexer
Enables combined terrestrial and non-terrestrial 5G FR2 signals on a single RF chain — key for hybrid ground station and UE designs in the 5G NTN ecosystem.
5G FR2 – TN + NTN – mmWav
Test & Measurement * NTN
RAMEChemu — NTN Channel Emulator
Dedicated NTN channel emulator that accurately reproduces satellite propagation effects — Doppler, delay spread, fading — for controlled lab protocol validation.
NTN Emulation – Doppler Sim – Protocol Test
