SHF Ultra Broadband

Amplifiers

Introducing our Range of Amplifiers

SHF has more than 30 years of experience in amplifier design and production. All the 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 comprises not only optical communications, but also satellite communications, high-speed pulse experiments, data transmission, radar and antenna measurements.

Ease of Use

40 Gbps, 6 V output of a SHF amplifier SHF S807 B Amplifier

With SHF amplifier modules, all necessary operating voltages are generated internally. Therefore, only one single power supply is needed. In addition, there are built-in safety features such as reverse-voltage protection and current regulators to eliminate the risk of accidental damage.

Each SHF amplifier has a gain control function to enable the amplifier gain to be reduced continuously by up to 3 dB. The SHF “S” and “D” series amplifiers (all parts starting with S or D in the product number) feature a software control to set the gain, output power and crossing.

Options

Internal bias tees and DC-returns can be added to the input or output ports. Matched pair options are also available for applications where the DUT has to be driven by two ‘identical’ signals in push-pull mode.

Linear Operation

In some modulation schemes, the optical modulator is driven with an electrical multi-level signal (e.g. for

QAM or PAM) or with an analog signal (e.g. for OFDM). Many of SHF amplifiers have been verified for their excellent performance with multi-level and analog signals. These amplifiers are marked blue in the table below. The SHF S807 B, for example, is an amplifier specifically designed for 4-level PAM4 signals.

Product Range

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