the max2750/max2751/max2752 are self-contained voltage-controlled oscillators (VCOs) intended for use in the 2.4ghz to 2.5ghz ISM band
The MAX2750, MAX2751, and MAX2752 are monolithic 2.4 GHz voltage‑controlled oscillators (VCOs) offered in an 8‑pin UMAX package. They integrate the tank circuit on‑chip, requiring only bypass capacitors and a supply voltage of 2.7 V to 5.5 V. The devices feature a low‑current shutdown mode and an internally matched 50 Ω output buffer.
Key specifications include guaranteed frequency ranges of 2400‑2500 MHz (MAX2750), 2120‑2260 MHz (MAX2751), and 2025‑2165 MHz (MAX2752), shutdown supply current below 1 pA, and typical output power of –3 dBm. The datasheet also details pin assignments, typical application circuits, layout recommendations, and thermal considerations for reliable operation.

The devices operate from a supply voltage of 2.7 V to 5.5 V.
The MAX2750 provides a guaranteed frequency range of 2400 MHz to 2500 MHz.
In shutdown mode the supply current is reduced to less than 1 pA.
All three devices are supplied in a miniature 8‑pin UMAX package.
