MAX2750AUA+T

Overview

The MAX2750AUA+T is a monolithic voltage-controlled oscillator (VCO) designed for the 2.4 GHz ISM band, specifically targeting automotive applications. It operates within a frequency range of 2.37 GHz to 2.47 GHz and delivers an output power of -3 dBm. The device requires a supply voltage between 2.7 V and 5.5 V, drawing a typical current of 21 mA. It features a tuning voltage range of 400 mVDC to 2.4 VDC with a push of 1.3 MHz/V. Secondary harmonics are suppressed to -30 dBc, and phase noise is rated at -235 dBc/Hz. Packaged in an 8-pin uMAX surface-mount case measuring 3.05 mm x 3.05 mm x 0.95 mm, it supports operation from -40°C to +125°C.
