Advantech 50W KU-Band BUC model SSPBMg-Kx50-CRE brand new in manufacturers box. Includes the connectors to make the AC cable and the M&C cable.
The part number for this BUC is GR0-3525A0-3N0 The N0 variant shows that the 10MHz is auto sensing. If external 10 MHz is applied the BUC will cut its internal 10MHz automatically
We were impressed with the small size and light weight of this BUC. Full frequency range of 13.75 to 14.5 GHz.

The Gain of the Amplifier is Set. Typical is 70 dB Your amp is Psat=50 Watts = +47 dBm Psat output Amp operates best at Plinear is 3 dB back off from Psat = +44 dBm (25 watts) Amp can be pushed to P1 dB = +46 dBm So with 0 db attenuation, 70 dB gain. Your input signal power level to meet Max output of +46 dBm = negative -24 dBm Max input
Sometimes your input can’t be adjusted to neg -24 dBm or lower, so you will use the attenuator to lower the Gain in order to not saturate the output of the amplifier over +46 dBm.
When you add dB’s of atten , it lowers the gain of the Amp. So if your Modulator or Upconverter output is Min -20 dBm, you must lower the level to less than -24 dBm using the Amp attenuator. Your gain in the amp is now 70 – 4 dB atten = 66 dB gain.
