FMVC003

Overview

The FMVC003 is a voltage-controlled oscillator (VCO) manufactured by Fairview Microwave, designed for RF applications within the 500 MHz to 1000 MHz frequency range. It features a center frequency of 750 MHz and operates with a tuning voltage span from 0 V to 19 V. The device exhibits a typical phase noise of -97 dBc/Hz and a pusher figure of 42 MHz/V. It draws a maximum supply current of 15 mA at a nominal 10 V supply. Housed in an 8-SMD module package measuring 4.40 mm x 4.40 mm x 1.90 mm, it supports operation between -40°C and 85°C.

Feature Summary

• Provides tunable oscillation across a 500 MHz to 1000 MHz bandwidth using a single DC control voltage input.
• Delivers stable signal generation with specified phase noise performance suitable for precision RF systems.
• Utilizes a compact surface-mount module form factor for integration into space-constrained circuit designs.

Applications

• RF test and measurement instrumentation
• Wireless communication transceivers
• Signal generation modules

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm mechanical footprint compatibility during design-in, noting the 8-SMD package dimensions. Ensure thermal management aligns with the specified operating temperature range. Cross-reference datasheet electrical parameters against system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed-frequency source is insufficient and electronic tuning within the UHF band is required. Evaluate the tuning linearity and phase noise specifications against system sensitivity requirements. Consider the power consumption limits and supply voltage constraints relative to the available board power rails. Verify that the SMD package style matches the target PCB assembly capabilities.

Part Context

This component belongs to the voltage-controlled oscillator category, distinct from fixed-frequency crystal oscillators or synthesizers. It serves as a core frequency generation element where variable output frequency is necessary. Unlike passive RF components, it requires active DC biasing to function. The specific model targets mid-band RF applications rather than microwave or baseband frequencies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part status is marked as obsolete, alternative sourcing may require evaluating generic VCO families with matching frequency ranges and pinout configurations.
