Maxim Integrated provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency PCB design, such as using a solid ground plane, minimizing trace lengths, and using 50Ω impedance-matched traces for the high-frequency signals.
The DS1855E-010+T&R requires a specific bias voltage and current to operate optimally. Ensure that the VCC pin is connected to a stable 3.3V power supply, and the VBIAS pin is connected to a voltage source that provides the recommended bias current (typically 10mA).
The DS1855E-010+T&R has an operating temperature range of -40°C to +85°C. However, it's recommended to derate the device's performance at higher temperatures to ensure reliable operation.
Start by verifying the power supply and bias voltage connections. Check for any signs of physical damage or overheating. Use an oscilloscope to verify the input and output signals, and consult the datasheet for troubleshooting guidelines specific to the device.
While the DS1855E-010+T&R is designed for 50Ω systems, it can be used in non-50Ω systems with some adjustments. However, this may require additional impedance matching components and careful signal integrity analysis to ensure optimal performance.
