The SHF 104 P is a two stage amplifier design using special monolithic
microwave integrated circuits (MMICs) inside special carriers to achieveultra wide bandwidth and low noise performance. The custom made
MMIC carrier is optimized for good input return loss between its interiorand the 50 Ohm outside hybrid technology. The computer optimized
broadband circuit is individually tuned for minimum passband ripple toget a near Bessel response. A voltage regulator IC makes the amplifier
insensitive to overvoltage and line ripple.

Gain reduction

All SHF amplifiers have a feature which allows the output gain to be reduced by up to approximately
3 dB by applying a negative voltage to the gain reduction pin.

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 to 15 V, 0.17 A DC
power supply and can be connected to the supply feed-through filter via anON / 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 increaseof the input return loss. For minimal degradation of amplifier rise time,these attenuators should have a bandwidth specification of greater 50 GHz(V/ 1.85 mm or 2.4 mm attenuators)!
6. An input signal of about 0.39 Vpp, equivalent to –4 dBm, will produce thefull swing output of 2 Vpp .
7. Higher input voltages will drive the amplifier’s output stage into saturation,leading to waveform peak clipping.
8. While using a reflective load, the output voltage has to be reduced to a safe
operating level below 2 Vpp according to the magnitudes of the reflections.
ATTENTION: At frequencies up to 20 GHz, a capacitive load can betransformed to an inductive one through transmission lines! With an output
stage driven into saturation this will lead to the immediate destruction of
the amplifier (within a few ps)!
9. Without DC power supplied to the amplifier, the input voltage should neverbe greater than 1 Vpp, equivalent to 4 dBm input power.
10. Hint: Pulse shape tuning of the amplifier has been performed after warm up
at about 40 °C case temperature. Considerably more over- and undershootwill be present at low temperature!
