Compression Characteristic @ 2140 MHz

Note 1: W-CDMA (Modulation Set-up for ACPR Mode); The Baseband I and Q input signals were generated using “Test Model 1 with 64 channels”

settings in the Agilent E3844C.

Note 2: The I/Q baseband amplitude and phase inputs were offset to achieve Sideband Rejection (SBR) levels. LO = +6 dBm, SSB Power = 0 dBm
