Amplifiers
SHF has almost 40 years of experience in amplifier design andproduction. All key MMICs used in our products are our own in-house
designs. The outstanding RF performance makes our amplifiers well
suited for a wide variety of applications in research & development.
This includes not only optical communications, but also satellite
communications, high-speed pulse experiments, data transmission,
radar measurements, quantum communication and computing.
The Fastest AmplifiersWith 100 GHz of 3 dB bandwidth, the SHF T850 C is the fastest amplifier SHF ever offered. Amplified PAM4 signals
are shown below.

Linear Operation
In some modulation schemes, the optical modulator is driven with an electrical multi-level signal (e.g. for QAM orPAM) or with an analog signal (e.g. for OFDM). SHF amplifiers have been verified for their excellent performancewith multi-level and analog signals.
Ease of Use
With SHF amplifiers, all operating voltages are generated internally. Therefore, only one single external power
supply is needed. In addition, built-in safety features such as reverse-voltage protection and current regulators
eliminate the potential risk of accidental damage.
Options
Internal bias tees can be added to the input or output ports. Matched pair options are also available for applications
where the DUT has to be driven differential or on multiple lines. In addition to that it is possible to mount two or
four amplifiers on one common heat sink, to place the amplifiers as close as possible to the DUT (e.g. an opticalmodulator with two or four inputs).

Each amplifier has a gain control function to reduce the gain continuously by up to 3 dB. The SHF “S”, “D” and “F”
series even provide a software control to set parameters like gain, output power, bandwidth and crossing (ifavailable for the particular amplifier type).
The “D” series features differential input, single-ended output linear drivers with excellent common mode
suppression. The SHF F840 A is SHF’s first fully differential amplifier.

Product Range
The table shows all the SHF amplifiers with their guaranteed small signal bandwidth and typical gain. For linear
applications, the guaranteed 1 dB power compression point indicates the possible output amplitude (note, forbinary applications the higher 3 dB compression is a more appropriate value).
