The ADRF6702 is a device that integrates a fractional-N synthesizer and a quadrature modulator. It operates in the frequency range of 1200 MHz to 2400 MHz and provides an internal LO frequency range of 1550 MHz to 2150 MHz. The device has excellent output power and IP3 performance, as well as wide baseband bandwidth and an SPI serial interface for PLL programming.
The ADRF6702 provides a compact quadrature modulator and synthesizer solution for RF output frequencies from 1200 MHz to 2400 MHz. It integrates a fractional‑N PLL, an internal VCO, and an IQ modulator, reducing external component count and board space.
The device is supplied in a 40‑lead 6 mm × 6 mm LFCSP package, operates from a 5 V supply (240 mA typical), and is rated for –40 °C to +85 °C. Detailed specifications, pin descriptions, timing characteristics, and evaluation‑board information are included.
