1. A transceiver, comprising:
- a baseband module configured to transmit a data signal;
a radio-frequency module configured to transmit the data signal at an extremely high frequency; and
wherein the baseband module is coupled to the radio-frequency module by way of a coaxial cable, the baseband module is configured to transmit a multiplexed signal to the radio-frequency module through the coaxial cable, and the multiplexed signal includes a control signal modulated onto a control carrier frequency and the data signal modulated onto an intermediate frequency.

Abstract
Disclosed are various embodiments for an extremely high frequency transceiver employing a baseband module and a radio-frequency module. The baseband module and the radio-frequency module are connected by a coaxial cable. The coaxial cable carries a multiplexed signal that may include a direct current component, a clock reference, a control signal, and an intermediate frequency signal. The control signal encodes one or more commands for controlling the operation of the radio-frequency module. Multiple radio-frequency modules may be employed in some embodiments.
