power foldback to 10% if RF power devices exceed
safe operating conditions
power foldback and shutdown if RF power devices
exceed safe operating currents
power foldback to 10% when supply voltage is 24 V to
26 V and 30 V to 32 V; shutdown when supply voltage
is < 24 V and > 32 V
power foldback to 10% at VSWR extremes;
continuous analog power foldback to maintain 100%
duty cycle into mismatched loads

<–60 dBc (EN 300 113 & EN 300 086)
<–50 dBc (EN 300 113)
Modulation fidelity <2%
Intermodulation –40dBc with interfering signal at –30dBc at TB9300
base station RF output. For Europe, 70dB ratio is
achieved using an external Circulator/Isolator with a
minimum isolation of 30dB and less than 0.5dB
insertion loss.
