The HSTX (amateur band) and HSTXC (commercial band) are compact S-Band transmitters designed for CubeSat missions. These transmitters operate at amateur and commercial bands and are compatible with the CubeSat standard.  These transmitters are ideal for space missions where a high data rate downlink is required.

The transmitters implement OQPSK and QPSK modulation with transmission data rates of up to 7.5 Mbps. They implement an open network encoding scheme based on the IntelSAT IESS-308 specification making this product compatible with low-cost commercial satellite receivers.
