Mh TO-8 Packaged Voltage Controlled Oscillators 300 MHz - 10 GHz MLO 60000 Series Features e PCB Compatible Low Cost Mil and Commercial Designs Broad Frequency Ranges Low Phase Noise Description M/A-COMs range of TO-8 voltage controlled oscillators (VCOs) provides excellent tuning linearity and phase noise for both narrow and broad bandwidth system applications. These designs use either a silicon bipolar transistor or FET device, dependent on frequency, as the negative resistance generator. The frequency of oscillation is determined by a varactor diode which serves as a volt- age variable capacitor in a tuned circuit. For wide band- width designs a GaAs hyperabrupt varactor is selected to give the greatest capacitance and therefore frequency, change against tuning voltage with the best linearity. For narrow bandwidth designs a silicon abrupt varactor offers the lowest phase noise performance. Careful selec- tion of the varactor diodes, manufactured in house by M/A-COM produces linear, monotonic tuning characteris- tics requiring only simple external driver circuits. This range of VCOs are constructed using discrete chip devices integrated into a conventional alumina MIC which is packaged in a standard TO-8 outline. The pack- age is hermetically sealed by resistance seam welding. This compact, rugged yet low cost construction allows simple installation on a conventional PCB and finds a wide range of applications in demanding military, hi-rel and commercial systems.

V3.00 Where oscillators with very fast tuning speeds over up to octave frequency bandwidths are required VCOs offer significant performance advantages. VCOs give improved LO frequency tuning speed and output power flatness in microwave receivers and rapid generation of output sig- nals in frequency agile transmitters. Where an oscillator with high frequency stability is required, as in radar or communications synthesizers and converters, the VCO can be used in a phase locked loop circuit. This pro- duces a frequency stability comparable to that of the ref- erence crystal oscillator. The phase locked loop circuit can be designed to stabilize a single output frequency or to vary the oscillator frequency continuously or in dis- crete steps as small as required. MLO 60000 Series oscillators can be qualified for high reliability and military requirements in addition to the standard commercial specification. A wide range of cus- tom designs is also available, please contact the factory to discuss your requirements. 1 North America: Tel.
