Design & Development (Boards and Kit)
F1280 Dual Variable 获得 Amplifier Evaluation Kit
The F1280EVK is a fully populated evaluation board that allows the customer to evaluate the F1280 dual VVA+VGA with integrated RMS detectors. The F1280 VGA 获得 范围s and switchable VGA2 inputs are controlled with serial communication input using a USB digital interface board that connects to the PC.
The F1280EVK consists of the following:
- F1280 Evaluation Board
- USB Digital Interface Board
- USB Cable (USB-A to USB-B micro)
The F1280 Evaluation Board consists of the following:
- SMA connectors for RF IOs and power supply connection
- Header pins for power supply and digital interface connection
- Jumper configurable power supply connection
- Clip-on test point access for voltage sense
- RF Balun SMD modules for unbalanced to balanced and balanced to unbalance conversion of RF IOs
