90DB Step Digital Programmable Attenuator 0.25DB TFT Display CNC High Isolation USB-C Port with SMA Female Connector Support TTL Serial Communication (9K-12GHz)

This programmable attenuator module mainly used in the fields where amplitude output control is required in radio - frequency and intermediate - frequency links. It has the advantages of wide frequency range, support for multiple communication methods, low power consumption, high attenuation accuracy, small attenuation step, fully shielded multi - cavity design, flat curve, and good isolation.;
Attenuation Range: 0 - 95.25 dB (the maximum attenuation is 90dB in practical application).
Minimum Attenuation Step: 0.25 dB.
Input/Output Impedance:
50.
Output Interface: SMA female connector (outer spiral and inner hole).;
Power Supply: Supports USB-C port for power supply (30W), and also supports TTL serial port communication.;
Communication Protocol: Supports both USB (STM32F4 virtual serial port, no need to set the baud rate) and FL serial port communication (baud rate is 9600).; There is a 1.3 inch full - color TFT and buttons for control. The RF port supports two - way communication and does not distinguish between input and output.
