MAX2608EUT

Overview

The MAX2608EUT+T is a voltage-controlled oscillator (VCO) from Analog Devices, housed in a SOT-23-6 package. It operates within a frequency range of 300 MHz to 500 MHz, with an alternative specification citing 45 MHz to 650 MHz. The device supports a supply voltage between 2.7 V and 5.5 V, drawing a current of 5.5 mA. Key electrical parameters include a tuning voltage range of 400 mVDC to 6 VDC, a power output of -10 dBm, and a secondary harmonic level of -30 dBc. It features a phase noise of -100 dBc/Hz and a push of 480 kHz/V. The component functions across temperatures from -40°C to +85°C.

Feature Summary

• Integrated varactor for tuning
• Low phase noise performance
• Differential or single-ended outputs

Applications

• General purpose IF oscillators
• GPS receivers
• Land mobile radio systems
• 902MHz to 928MHz ISM band applications

Procurement Notes

Verify the specific frequency range variant required, as documentation references both 300-500 MHz and 45-650 MHz ranges. Confirm the suffix 'T' indicates reel packaging if applicable. Ensure the manufacturer is identified correctly as Analog Devices or Maxim Integrated. Check RoHS compliance status before integration. Validate that the SOT-23-6 package matches the design footprint requirements.

Selection Notes

Select this component for applications requiring low jitter and wide application frequency ranges. Consider the small size and integrated varactor for compact designs. Evaluate the single supply voltage requirement against system power constraints. Assess the need for differential versus single-ended outputs based on circuit topology. Verify thermal operating limits for the intended environment.
