A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the edge of the board to minimize the length of the RF traces. A via-stitched ground plane is also recommended to reduce electromagnetic interference (EMI).
The device requires a single 5V supply voltage and a bias current of 10mA to 20mA. A voltage regulator and a bias resistor network can be used to set the bias voltage and current. The bias voltage should be set to 2.5V to 3.5V for optimal performance.
The SMV1705-079LF can handle up to 2W of continuous wave (CW) power and up to 10W of peak power for short pulses (<10us). However, the device should be derated for high-temperature operation and high-power applications.
The SMV1705-079LF has an input impedance of 50 ohms and an output impedance of 50 ohms. A pi-network or a T-network can be used to match the impedance of the device to the system. The matching network should be designed to optimize the return loss and insertion loss.
The SMV1705-079LF operates over a temperature range of -40°C to 85°C. However, the device should be derated for high-temperature operation to ensure reliable performance.
