Abstract
This document describes the activities performed during the first phase switch tuning test performed during CPV. The objective of this test 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 test was performed before the tuning of the front-end modules amplifiers. The test was performed only on 30 and 44GHz RCAs as planned.
