The FMVC31018 is highly reliable low noise Voltage Controlled Oscillator (VCO) that operates across 850 MHz to 890 MHz with a tuning voltage range from 0V to 5V. Impressive typical performance includes generated output power of +8 dBm, 2nd Harmonic Suppression of -5 dBc, phase noise of -99 dBc/Hz @ 10 KHz offset, and tuning sensitivity of 40 MHz/V. The design incorporates internal voltage regulation and reverse DC protection, with a bias voltage range from +9V to +15V. The rugged and compact coaxial package assembly supports SMA female connectors, RFI and ground pins. The VCO has an operational temperature range of -40°C to +85°C and is designed to meet a variety of MIL-STD-202 test conditions including shock, vibration, altitude, and humidity.
