The ADRF6603 is a high dynamic range active mixer with integrated phase-locked loop (PLL) and voltage controlled oscillator (VCO). The PLL/synthesizer uses a fractional-N PLL to generate a fLO input to the mixer. The reference input can be divided or multiplied by a configurable integer multiplier. This allows the frequency range to be from 2100 MHz to 2600 MHz.
The ADRF6603 is a high‑dynamic‑range active Rx mixer that incorporates a fractional‑N phase‑locked loop and voltage‑controlled oscillator. It converts a single‑ended 50 Ω RF input to a differential 200 Ω IF output and supports internal LO frequencies from 2100 MHz to 2600 MHz.
Key specifications include an RF input frequency range of 1100 MHz‑3200 MHz, input P1dB of about 14.8 dBm, IIP3 of 28.5 dBm, a voltage conversion gain of 6.7 dB, and a 3 dB IF bandwidth of 500 MHz. The device is supplied in a 40‑lead 6 mm × 6 mm LFCSP and operates from –40 °C to +85 °C, making it suitable for cellular base‑station front‑ends and other RF applications.
