Phase 3D's V and U band transmitters and receivers are shown installed into bay 3 of the spacecraft during recent testing at the Phase 3D Laboratory in Orlando, Florida. At top center is the V and U band receiver, while the V and U band antenna switching relays are shown at the top right. Shown along the bottom row (from left to right) are the U-band exciter, the "piggy back" module containing the U-band HELAPS modulator and high power amplifier, and the V-band high power transmitter/amplifier.
