Description
The SHF P100 A broadband amplifier is the RoHS compliant successor of the popular SHF
100 AP. The SHF P100 A is a two stage, wideband RF amplifier featuring flat gain and low group delayvariation. By use of proprietary monolithic microwave integrated circuits (MMICs) a 1 dB compression
point of 13 dBm and low noise figure are achieved. An internal voltage regulation protects the amplifier
against accidental reverse voltage connection and makes it robust against line voltage ripple.
In addition the amplifier is characterized by a gain control input for up to 3 dB gain reduction.

Typical Noise FigureThe measurement had been performed using a FSW85 Spectrum Analyzer by Rhode & Schwarz. The
noise figure defines the degradation of the signal-to-noise ratio when the signal passes the amplifier. An
ideal amplifier would amplify the noise at its input along with the signal. However, a real amplifier adds
some extra noise from its own components and degrades the signal-to-noise ratio. Please note that thisapplies to small signals only. When the amplifier is used close to or in its saturation region additional nonlinear effects will impact the signal-to-noise ratio and the signal waveform.

Handling Instructions
To operate the amplifier a positive supply voltage of approximately +9 V must be applied.
The gain can be adjusted by applying a voltage of 0 to -5 V. If this pin is left open, the amplifier will havemaximum gain. By reducing the gain the crossing will shift. Typical characteristics are shown in thefollowing diagram for an input voltage of 0.5 V with 50% crossing.

For permanent mounting remove the heat sink from the amplifier. In that case please ensure thatadequate cooling of the amplifier is guaranteed. It is recommended to use thermal paste or a thermal gap
pad for the mounting. In order to separate the heat sink from the amplifier, remove the four screws on theheat sink. Please note, thermal paste is used between the heat sink and the amplifier housing.

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 power supply and can be connected to the supply
feed-through filter via an ON / OFF switch.

4.

It make sense to use the minimum supply voltage. A higher one increases the power dissipation of theinternal 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. Forminimal degradation of amplifier rise time, these attenuators should have a bandwidth specification ofmore than the amplifier bandwith.

6.

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

7.

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.

8.

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 immediate
destruction of the amplifier (within a few ps)!

9.

2

For the DC-connections flexible cable 0.2…0.5 mm / AWG 24…20 are recommended. A maximum
soldering temperature of 260 °C for 3 seconds is recommended for the feedthrough (positive supply
voltage and bias tees pin). The ground pin requires significantly more heat as it is connected to the solid
housing.
