A module for constructing a modular transmitter is disclosed. The module contains antenna elements along the front edge of a base. RF circuitry is fabricated on both the top and the bottom sides of the base. The base contains heat pipes to carry heat away from RF circuitry. The base is made to be plugged into a mounting block which provides electrical signals to the module and acts as a sink for the heat removed by the heat pipes.

Modular transmitter and antenna array system

A stripline transition between two layers of a multilayer microwave stripline assembly. Two stripline layers are sandwiched between metal plates. The metal plates have formed therein complementary curved transition regions and force a stripline to undergo a gradual transition from a first layer to a second layer of the assembly.
