Hermetically sealed coaxial microstrip launchers with improved parameters for microware electronics

Hermetically sealed coaxial microstrip launchers with coaxial lines 3.5/1.52 and 7/3.04 mm are designed. The main parameters of launchers are given in table. The launchers provide effective parameters of devices with WSWR level 1.3 and RF insertion loss level 0.2 dB. The frequency range for two types of launchers makes up from DC to 18 GHz. The impedance is 50 Omega
