* Ultra Low Noise, Low Harmonic 90 to 120 MHz VCO
The model MW500-1163 voltage controlled oscillator (VCO) provides an unprecedented low phase noise of 143 dBc/Hz at 100 kHz offset, 122 dBc/Hz at 10 kHz, 100 dBc at 1 kHz and 160 dBc/Hz at 1 MHz. Tuning voltage is 0 to 10 V, supply is +5 V at 20 mA and harmonics are below 18 dBc. Pushing and pulling are only 0.01 MHz/V and 0.2 MHz, respectively. Power output is +5 dBm up to 100 MHz and +1 dBm at 120 MHz. The VCO can also be supplied without the harmonic filter, in which case the output is +5 dBm up to 140 MHz (at 13 V tuning). Harmonics are 5 dBc with this option. Both versions are very stable; temperature drift is only 0.02 MHz/°C. They can also (with 0.5 Vt ) cover the 88 to 108 MHz FM broadcast band, providing the basis for a very low noise, low cost FM transmitter for state-of-the-art audio. Size: 0.50" * 0.15".
