The ADRF6604 is a high dynamic range active mixer with integrated phase-locked loop (PLL) and voltage controlled oscillator (VCO).
The ADRF6604 from Analog Devices is a high‑dynamic‑range active mixer that integrates a fractional‑N phase‑locked loop and voltage‑controlled oscillator. It operates with an internal LO frequency range of 2500 MHz to 2900 MHz and supports RF input frequencies from 1200 MHz to 3600 MHz. The device is supplied in a 40‑lead, 6 mm × 6 mm LFCSP package and is RoHS‑compliant.
Key features include a voltage conversion gain of 6.8 dB, a 500 MHz IF 3‑dB bandwidth, programmable 3‑wire SPI control, and a wide operating temperature range of –40 °C to +85 °C. Detailed pin configurations, timing characteristics, and absolute maximum ratings are provided for design integration.
