Handling Instructions
To operate the amplifier a positive supply voltage of approximately +5 V must be applied.
Please do never exceed the maximum values given in the above table. This will severely damage theamplifier.

GainThe gain can be reduced by applying a negative voltage to the Gain control pin “Gain”. If it is left open
the amplifier will operate with its maximum gain.
Note: If the amplifier is driven in saturation the effect of the gain control is reduced.

Examples:Gain control = open

Gain control = -5 V

Amplitude = 3.75 V

Amplitude = 3.16 VCrossing
The crossing can be adjusted by applying a voltage to the cross point control pin “Crossing”. If it is left
open the output signal will have approximately 50% crossing. In case this is considered to be accurateenough for the application the cross point control pin “Crossing” can be left open.
Examples:Crossing control = open

Crossing control = -5 V

Crossing control = +5 V

Crossing = 52 %Crossing = 65 %Crossing = 38 %SHF reserves the right to change specifications and design without notice – SHF 804 M - V002 – Jan 12, 2017

For permanent mounting remove the heat sink from the amplifier. In that case please ensure that adequatecooling of the amplifier is guaranteed. It is recommended to use thermal paste or a thermal gap pad for themounting. In order to separate the heat sink from the amplifier, remove the four screws on the heat sink.

ATTENTION!
Electrostatic sensitive GaAs FET amplifier1.

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 a well regulated 4.5…5.5 V, 0.3 A DC power supply and can beconnected to the supply feed-through filter via an ON / OFF switch.

4.

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 ofgreater 50 GHz (V/ 1.85mm attenuators)!

5.

An input signal of about 0.5 Vpp will produce saturated output swing of about 3.5 Vpp.

6.

Higher input voltages will drive the amplifier’s output stage into saturation, leading to waveform peakclipping.

8.

Saturated output voltages can only be used without damage while the amplifier is connected to a 50
Ohm precision load with a VSWR of less than 1.2 or better than 20 dB return loss up to 40 GHz.

9.

While using a reflective load the output voltage has to be reduced to a safe operating level according
to the magnitudes of the reflections.
ATTENTION: At radio frequencies a capacitive load can be transformed to an inductive one throughtransmission lines! With an output stage driven into saturation this may lead to the immediatedestruction of the amplifier (within a few ps)!

10. The input voltage should never be greater than 1 Vpp equivalent to 4 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.
