The objective of this test, composed of two steps, is to find the optimal bias currents to the front-end phase switches that balance the wave amplitude in the two-phase switch states. An optimal balance has an impact on the receiver isolation, therefore the first part of the test (P_PVP_LFI_0004_01, namely tuning) was performed before the tuning of the front-end modules amplifiers. The second part (P_PVP_LFI_0004_02, namely verification) was performed after the tuning of the front-end modules to verify the impact on phase switch balancing of different amplifiers biases. The test was performed only on 30 and 44GHz RCAs as planned.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
