Description:
The programmable attenuator boasts wide frequency range and supports for various communications, featuring low power consumption, high attenuation precision, small attenuation step, fully shielded multi-cavity design, flat curve, and good isolation.

It is mainly used in the fields where the amplitude output needs to be controlled on the RF and IF links.

Module Parameters:
- Power supply voltage: +5V (powered via TYPE-C cable)
- Input and output impedance: 50Ω
- Output interface: SMA female
- Minimum attenuation step: 0.25DB
- Maximum input power: 30dBm (1W)
- Size: 6.8 x 4.8cm/2.7 x 1.9" (LxW) (excluding the size of SMA); height: 2.5cm/1"
- Provided communication protocol: support USB and TTL serial communication at the same time
- Input loss and standing wave parameters (refer to the measured value of vector network)
- Module weight: 120g/0.3 lb

Features:
1. Separation of core attenuation chip and MCU main control shield
2. All-aluminum alloy housing; multiple cavities are used inside the attenuation chip
3. DC-6GHz frequency band; 0.25DB minimum step; maximum 90DB attenuation
4. TYPE-C port supports power supply + communication; supports TTL serial communication
5. 1.3" full-color TFT with button control
6. Radio frequency ports enables two-way communication, that is, no distinction between input and output
7. With SMA male connectors to input and output
8. Host computer communication software provided

Package Included:
- 1 x Attenuation Module
- 1 x Type-C Cable

Module Communication Protocol (all commands are terminated with the Enter key + line feed):
1. Send the attenuation coefficient command: change the attenuation coefficient (the end symbol is "enter /n/r"); the format is: att-xxx.xx
2. Response value signal: The format is: attOK
3. When using TTL serial communication, the baud rate is 9600
4. Read data format: READ (Enter/n/r)
5. USB communication is STM32F4 virtual serial port, no need to set baud rate
