The ADF4002-EP frequency synthesizer is a 400MHz bandwidth frequency synthesizer that supports 2.7V to 3.3V power supply, uses a 3-wire serial interface, and can implement clock conditioning, clock generation and IF LO generation.
The ADF4002-EP is a frequency synthesizer designed to implement local oscillators in upconversion and downconversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector, a precision charge pump, and programmable reference and N dividers.
Key specifications include a 400 MHz bandwidth, support for military temperature ranges (–55°C to +125°C), and a separate charge pump supply allowing extended tuning voltage in 3 V systems. The device supports defense and aerospace applications meeting AQEC standards.
