The SHF 100 CP is a three 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.

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.

The amplifier is supplied with a heatsink (not shown) witha thermal resistance of 1.5K/W. For permanent mounting,the heatsink can be removed. Adequate cooling must beensured.

User Instructions
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 any regular 11…15 V, 1 A DC power supply and can beconnected to the supply feed-through filter via an ON / OFF switch.

4.

The minimum supply voltage is 11 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 returnloss.

6.

An input signal of about 1.8 Vpp equivalent to 9 dBm will produce saturated output swing of
12.6Vpp.

7.

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

8.

Saturated output voltages can only be used between 10 MHz and 40 GHz 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 26 GHz.

9.

While using a reflective load the output voltage has to be reduced to a safe operating level below
6.5 Vpp according to the magnitudes 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 theimmediate destruction of the amplifier (within a few ps)!

10. The input voltage should never be greater than 2 Vpp equivalent to 10 dBm input power.
The input voltage without DC power supplied to the amplifier should never be greater than 2 Vppequivalent to 10 dBm input power.
11. Hint: Pulse shape tuning of the amplifier has been performed after warm up at about 35°C casetemperature. Slightly more over and undershoot will be present at low temperature!
