Principals of Operation
3.1 Introduction
This section contains the functional description of the MAF800-100S multi-carrier power amplifier.
3.2 RF Input Signal
The maximum composite input power shall not exceed – 4 dBm. The reference source signal shall not
exceed the base station manufacture minimum requirements for intermodulation distortion. For proper loop
balance, the out of band components of the input signal shall not exceed –40 dBc. The input VSWR should
be 2:1 maximum
3.3 RF Output Load
The load impedance should be equal to or better than 1.5:1 in the operating band for good power transfer to
the load. If the amplifier is operated into a filter, it will maintain its distortion characteristics outside the
signal band even if the VSWR is infinite. Provided the reflected power does not exceed one-watt. A
parasitic signal of less than one-watt incident on the output will not cause distortion at a higher level than
the normal forward distortion
