Title: Phase shifter measurement circuit
Inventor: TAKAHASHI TADAO
IPC: G01R29/10
Filed: 1991-10-23
Abstract: PURPOSE:To improve the measurement accuracy of a phase shift measurement circuit by calculating the insertion loss and insertion phase shift of the phase shifter of a system to be measured from the average value of synthesized signals. CONSTITUTION:By fixing the state of the system (b) to be measured of an antenna module to be measured, the phases of systems (b) and (c) are measured with a network analyzer 4 by shifting the phases in 16 steps from 0 deg. to 360 deg.. Then a CPU 6 retrieves the states of the systems (a) and (c) having the maximum measured amplitude values. By setting the phase shifting amounts of the systems (a) and (c) to the retrieved states and changing the phase shifting amount of the system (b) to be measured from 0 deg. to 360 deg., amplitudes and phases of RF signals received in 16 states are measured. The CPU 6 calculates the state where the phase shifting amount is inverted by 180 deg. against the phase shifting amount retrieved states of the systems (a) and (c) and measures the amplitudes and phases of the received RF signals by setting a phase shifter to the phase shifting amount and changing the phase shifting amount of the system (b) from 0 deg. to 360 deg.. Then the CPU 6 calculates the insertion loss and insertion phase shift of the system (b) from the average value of these synthesized signals.
