Description

The ISIS UHF uplink/UHF downlink transceiver is a full-duplex communication system for CubeSat TT&C applications. The radio can operate in commercial bands of the UHF frequency spectrum. It is low power, low mass, and highly configurable, offering the flexibility of changing data rates and frequencies in flight. This radio is tailored for CubeSat missions and cross-compatible with other subsystems such as onboard computers and antenna systems.
