Ultra Linear RF Amplifier for DiRaGen
The PostAmp 1-150 was especially
developed as post amplifier for the DiRaGen 30.This amplifier increases the
DiRaGen`s output level for about 30dB from -10dBm to +20dBm (100mW).
This delivers enough power for
an optional power amplifer.
Amplifiers for DRM signals need
an ultra linear design to avoid compression effects which will degrade the
excisting Signal-to-Noise Ratio (SNR). This is guaranteed when the RMS output
power level (measured thermically) is about 10-14dB (depending on Crest Factor)
below the declared compression point (P-
1dB) for peak envelope power (PEP).
The temperature compensated amplifier
is housed in a robust oversized aluminium cabinet for passive cooling.
Due to the linear design the
unit is best suited for all analog and digital modulated signals.
