Q Band Transmitter

OVERVIEW

Q Band Transmitter System
Space Heritage Q2 2023

Our compact Q Band Transmitter system is a miniaturized plug&play solution for Cubesats and small satellites, specifically designed for high reliability and radiation tolerance.
Suitable for LEO and GEO missions, it offers a Q Band Transmitter and a high gain dual polarized lens horn antenna.
The system offers high linearity upconversion for existing on-board S-L band systems or it can act as standalone Q Band Transmitter.
The internal low power modulator is compatible with CW/ASK/OOK/FSK modulations and beacon signal generation.
Support of numerous interfaces and communication protocols ensure compatibility with all popular Cubesat and Smallsat platforms.
Robust construction, component qualification and EMI shielding meet the requirements for space and harsh environments.
