Description
The SHF 826H is a two stage amplifier based on special designed monolithic microwave integrated circuits(MMICs) to achieve ultra wide bandwidth and low noise performance.
The amplifier will be delivered with a removable Bias Box. This feature allows the use without any
additional bias circuitry. The box should be used with the included ribbon cable which is made for theconnection to standard laboratory connectors (for power supply and voltage level detector).
Due to this concept the amplifier provides the same ease of use like all other well known SHF laboratory
amplifiers. Nevertheless the use without the bias box offers a flexibility which makes this amplifier to theideal product for system applications.

Applications
Optical Communications

High-Speed Pulse ExperimentsSatellite Communications



Research and Development

Antenna MeasurementsData Transmission

Available Options


01: DC return on input (max. ±1.75 V, max. 35 mA)

02: Built-in bias tee on input



03: DC return on output (max. ±1.75 V, max. 35 mA)



04: Built-in bias tee on output



MP: Matched Pair. Two amplifiers will be matched. A matched pair has a gain variance ≤ 1dB,a propagation delay variance ≤ 5ps and an output amplitude variance ≤ 0.5V

The following options cannot be combined:
01 and 02
03 and 04

Notes:
1: To maintain maximum amplitude keep the OVC-Input left floating or VOVC as high as ~ +11 V (max 12.6 V).
2: If the output amplitude is reduced a crossing control voltage is required to get an output eye with 50% crossing.
