2 Description The SHF 100 BPP is a two stage amplifier design using special monolithic microwave integrated circuits (MMICs) inside special carriers to achieve ultra wide bandwidth and low noise performance. The custom made MMIC carrier is optimized for good input return loss between its interior and the 50 Ohm outside hybrid technology. The computer optimized broadband circuit is specially tuned for minimum pass band ripple. A voltage regulator IC makes the amplifier insensitive to reverse voltage and line ripple.

8 User Instructions ATTENTION! Electrostatic sensitive GaAs FET amplifier 1. To prevent damage through static charge build up, cables should be always discharged before connecting them to the amplifier! 2. Attach a 50 Ohm output load before supplying DC power to the amplifier! 3. The supply voltage can be taken from any regular 9 12 V, 0.5 A DC power supply and can be connected to the supply feed-through filter via an ON / OFF switch. 4. The minimum supply voltage is 9 V. A higher one increases the power dissipation of the internal voltage stabilizer. 5. Using a 3 db or 6 db input attenuator will result in a 6 db or 12 db increase of the input return loss. For minimal degradation of amplifier rise time, these attenuators should have a bandwidth specification of greater than 40 GHz (K/ 2.9mm attenuators)! 6. An input signal of about 1.1 V pp will produce saturated output swing of 7 V pp. 7. Higher input voltages will drive the amplifier s output stage into saturation, leading to waveform peak clipping. 9. While using a reflective load the output voltage has to be reduced to a safe operating level below 5.0 V pp according to the magnitude of the reflections. ATTENTION: At frequencies up to 20 GHz a capacitive load can be trans-formed to an inductive one through transmission lines! With an output stage driven into saturation this may lead to the immediate destruction of the amplifier (within a few ps)! 10. The input voltage should never be greater than 2 V pp equivalent to 10 dbm input power. The input voltage without DC power supplied to the amplifier should never be greater than 2 V pp equivalent to 10 dbm input power. 11. Hint: Pulse shape tuning of the amplifier has been performed after warm up at about 40 C case temperature. Slightly more over and undershoot will be present at low temperature!
