K Band Transmitter


1W K and Ka Band Transmitter for Small Satellites, Cubesats and drones 17.8-20.2 GHz

Our compact K Band Transmitter is an highly-integrated and efficient solution for small satellites and SOTM terminals, specifically designed for low size, mass and power consumption required to meet state-of-the-art customer requirements.
Suitable for large variety of missions, from very high to ultralow data-rates, it offers high linearity upconversion for existing on-board S-L band systems, as well as a fully integrated low-power ASK/FSK/PSK modulator and beacon 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.
