The invention relates to the technical field of a transmit-receive
frequency conversion channel, and discloses a
millimeter wave 16-channel transmit-receive
frequency conversion channel
assembly, which mainly adopts a mixed design of an MMIC bare
chip and an LTCC circuit and realizes a microminiature design through one or more
frequency conversion. The transmit-receive frequency conversion channel
assembly is in a three-layer structure on the whole, wherein the upper layer comprises a
power control portion, the middle layer is a frequency conversion circuit portion and the lower layer comprises 16 paths of
waveguide interfaces. The frequency conversion circuit portion comprises 16 paths of receiving channels, one path of emission channel and a
local oscillator processing circuit. The receiving channels and the emission channel share the 16 paths of
waveguide interfaces; transmit-receive time-sharing power supply is realized; channel switching is carried out through a
radio frequency switch; power supply and control signals between the
layers are connected through a miniature low-frequency connector;
radio frequency signals are connected through a
radio frequency isolator; and the
layers are internally connected through via holes. Therefore, the
millimeter wave 16-channel transmit-receive frequency conversion channel
assembly realizes high-density integration of
millimeter wave multi-channel transmit-receive frequency conversion channels, is small in size, light in weight and high in environment adaption capability, improves working stability and reliability of the
system in various environment conditions, and meets the
future trend of transmit-receive frequency conversion channel
miniaturization.
