METHOD AND DEVICE FOR REGULATING THE POWER OF MILLIMETER WAVES FOR A V-BAND TR MODULE

摘要

The invention relates to a method for regulating the power of millimetre waves for a V-band TR module. According to said method, the power output is detected and regulated at a constant level with a regulating electronics system, by means of a damping member. The invention provides that for transmission, for operation at a frequency in the 60 GHz range and higher, a first SPDT (single pole double throw) MMIC switch is used as a regulated damping member and a second SPDT MMIC switch which acts as a transmit-receive changeover switch is used as a power output detector. For reception, both SPDTs are used as switches. Overall, the power regulation for the entire TR module results in an increase of the module yield through compensation of chip leakage and temperature effects. The multiple use of the SPDT MMICs as switches, damping member and power detector saves costs.
