LF-13GHz 0–31.5dB RF Digital Step Attenuator 9KHz–13GHz Parallel Port Control

Description:
The 13GHz digital step attenuator core board comes with a STM32 main control board. Thus, the product can be used as a digital programmable attenuator.

Basic Parameters:
- Frequency range: 9KHz-13GHz (signal link should not contain DC)
- Maximum input power: 30DBM (1W)
- Input and output impedance: 50 ohms
- Input and output interfaces: 26.5G SMA female connectors
- Core board size: 5cm x 5cm/2" x 2"
- Attenuator core board: By default, the core board only supports parallel port mode when it is purchased separately. But the core board supports parallel port mode and SPI serial port mode when it is purchased as a whole with a main control board
- For specific insertion loss and error, see the S11 and S21 curves
