RECEIVING-TRANSMITTING MODULE OF APAA Russian patent published in 2025 - IPC H05K7/20 H01Q21/00 H01Q1/02 

FIELD: radar equipment.

SUBSTANCE: invention relates to radar engineering, particularly to active phased antenna arrays (APAA). Proposed is the APAA receiving-transmitting module (RTM), including: a heat-removing base on which heat-generating radioelectronic components are arranged, volumetric heat accumulator (HA) based on a phase transition of 1st kind, with an unsealed housing made of a material with high heat conductivity, wherein one of the HA walls is the heat-removing base, which is the RTM multilayer board lower metallization, and on the opposite wall there is a through hole, wherein the working medium of the HA has a melting point of 60 °C ≤ T_Fp ≤ 80 °C, volume of HA WM is determined from relationship: K×(τ×P_RTM)/ρ_h.a.c_p≤V_o.w.≤K×(0.5λ×0.5λ×0.5λ), where P_RTM is average heat power dissipated by RTM; τ is time of operation of RTM; λ is the operating wavelength of the RTM; ρ_h.a. is average specific density of HA WM; c_p is specific heat capacity of phase transition HA WM; K is a structural coefficient corresponding to the share of HA WM in the total volume of the RTM.

EFFECT: longer operation time of the receiving-transmitting module (RTM) of an on-board active phased antenna array.
