Harmonics and intermodulation usually are dominated by the power amplifier and vary depending on the power level and amplitude statistics.
Standard circulators and isolators for GSM base station applications are designed to sustain RF power up to 100 W CW (where CW stands for continuous wave) with intermodulation distortion (IMD) in the range of -65 to -75 dBc.
RF sourcing is used if test specifications call for receiver sensitivity tests, bit error rate tests, adjacent channel rejection, two-tone intermodulation rejection, or two-tone intermodulation distortion.
These maps can be used to select the best device operating conditions and matching network for high power levels, Typical data that can be mapped are output power, intermodulation distortion, adjacent carrier power ratio and gain.
RF power amplifier (RFPA) nonlinearities introduce third-order intermodulation distortion (IMD) to the amplifier output signal when driven by a multitone input signal.
Operation is in the DC to 8 GHz bandwidth with 3rd order intermodulation at -165 dBc and VSWR better than 1.02:1 at DC-2 GHz.
GSM 11.26 specifies that the maximum level of spurious emission and intermodulation products shall not be greater than -36 dBm (250 nW) in the 9 kHz to 1 GHz frequency band and -30 dBm (1 [mu]W) in the 1 to 12.75 GHz frequency band.
The device operates in the DC to 8 GHz bandwidth with intermodulation better than -165 dBc and a VSWR of 1.06 (max).
The R3681 has a dynamic range of 142 dBm with a specified average noise level of -156 dBm/Hz and 26-dBm typical third-order intermodulation distortion.
