Mh Broadband Voltage Controlled Oscillators 0.5 - 20 GHz MLO 50000 Series Features e Broadband Frequency Ranges Fast Tuning Speed Low Tuning Voltage High Output Power High Reliability Description M/A-COMs range of broadband voltage controlled oscil- lators (VCOs) offers excellent tuning characteristics over octave frequency bandwidths for wideband systems applications. These designs use a negative resistance transistor oscillator, for the lower frequencies this is a sil- icon bipolar device with GaAs FET devices extending the range to 20GHz. The frequency of oscillation is deter- mined by one or more GaAs hyperabrupt varactor diodes acting as voltage variable capacitors in a resonant microstrip circuit. Careful selection of the varactor diodes, manufactured in house by M/A-COM, produces a vety large capacitance change together with a high degree of linearity which greatly simplifies the external voltage driver circuit required. This design provides extremely high tuning rates, limited primarily by the internal impedance of the external driver circuit. 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 an 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, with the connectors removed the devices can be integrated directly into microstrip or stripline circuits.

V3.00 These VCOs have a wide variety of applications where highly reliable oscillators with fast frequency agility over wide bandwidths are required. VCOs give improved LO frequency tuning speed and output power flatness in wideband EW receivers and rapid generation of jamming signals in ECM transmitters. The wide bandwidths and compatibility with digital to analog converters make these VCOs ideal building blocks for digitally tuned oscillators operating over multi-octave bandwidths. 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 VCO assemblies for multi-octave applications.
