High Linearity Voltage Controlled Oscillators 2 - 18 GHz MLO 30000 Series Features High Tuning Linearity Low Phase Noise Fast Tuning Speeds High Output Powers High Reliability Description M/A-COMs range of high linearity voltage controlled oscillators (VCOs) provides excellent tuning linearity and phase noise over the moderate frequency bandwidths required for most systems applications. These designs use a resonator stabilized silicon bipolar transistor as a negative resistance generator with a varac- tor diode serving as a voltage variable capacitor in a tuned circuit to vary the frequency of oscillation. This fundamental oscillator design is extended to 18 GHz with an integral frequency doubler. The MLO 30000 series uses a GaAs hyperabrupt junction varactor diode for optimum frequency tuning linearity. Careful selection of the varactor diodes, manufactured in-house by M/A-COM produces a very large capacitance change together with a high degree of linearity which greatly simplifies the external voltage driver circuit required. M/A-COM VCOs are constructed using discrete chip devices integrated into a conventional alumina MIC with laser welding of the finished VCO package providing a hermetic seal. This compact, rugged construction makes these VCOs suitable for the most severe environmental conditions encountered in military and hi-rel applica- tions. The coaxial packages have removable SMA con- nectors, allowing the devices to be integrated directly into microstrip or stripline circuits. Specifications Subject to Change Without Notice. M/A-COM, Inc. V3.00 VCOs have a wide variety of applications where oscilla- tors with very fast tuning speeds over up to octave fre- quency bandwidths are required. VCOs give improved LO frequency tuning speed and output power flatness in radar receivers and rapid generation of jamming signals in ECM transmitters. Where an oscillator of high frequen- cy stability is required, as in radar and communications synthesizers or frequency converters the VCO can be used in a phase-locked loop circuit. This produces a fre- quency stability comparable to that of the reference crys- tal oscillator. The phase-locked loop circuit can be designed to stabilize a single output frequency or to vary the oscillator frequency either continuously or in discrete steps as small as required. The standard VCOs described cover a range of common- ly used bandwidths with a choice of three output pow- ers. M/A-COM also manufactures a wide range of custom designs to meet specific system specifications and VCOs integrated with other components.
