The SHF 801 P is ideal for use as a preamplifier for extremely high bandwidth devices, e.g.
photodiodes, spectrum analyzers, network anlyzers, test equipment, etc.
A single stage amplifier design is employed using special monolithic microwave integrated circuits(MMICs) inside special carriers to achieve ultra wide bandwidth and low noise performance. Thecustom made MMIC carrier is optimized for good input return loss between its interior and the 50Ω
outside hybrid technology. The computer optimized broadband circuit is designed for minimum
pass band ripple. A voltage regulator IC makes the amplifier insensitive to reverse voltage and line
ripple.

Jitter: 299 fs

Jitter: 521 fs

The specification for jitter is based on the measurement using the 63 GHz sampling module andprecision time base. The figure of <600 fs is not deconvoluted from the total system jitter; it is thefigure displayed on the oscilloscope for the whole system (multiplexer, amplifier, sampling head andoscilloscope).
To deconvolute the jitter, we use the following formula:amplifier jitter = [(total jitter)2 - (input signal jitter)2]½This yields a jitter value of <500 fs.
It is taken at an output level between 1 and 2 V. Using a standard time base and 50 GHz sampling
module, we specify a maximum jitter figure of 1ps.

Gain reduction function

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

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.

The supply voltage can be taken from any regular 5.2…9 V, 0.13 A DC power supply and can beconnected to the supply feedthrough filter via an ON/OFF switch.

3.

The minimum supply voltage is 5.2 V. A higher one increases the power dissipation of the internal
voltage stabilizer.

4.

Using a 3 dB or 6 dB input attenuator will result in a 6 dB or 12 dB increase of the input returnloss. For minimal degradation of amplifier rise time, these attenuators should have a bandwidth
specification of greater than 65 GHz (V/1.85mm attenuators)!

5.

An input signal of about 1.6 Vpp (equivalent to 8 dBm) will produce a saturated output swing of
2.8Vpp.

6.

Higher input voltages will drive the output stage of the amplifier into saturation, leading towaveform peak clipping.

7.

The input voltage should never be greater than 1.6 Vpp equivalent to 8 dBm input power.The input
voltage without DC power supplied to the amplifier should never be greater than 2.8 Vpp(equivalent to 13 dBm input power).
