Ceramic GaAs Constant Gamma Tuning Varactor Diodes The ML46450 and ML46470 Series of tuning varactors are hyperabrupt junction gallium arsenide devices featuring a constant gamma. These series offer especially high “Q factors” (up to 4000) that permit excellent tuning performance from VHF to 40 GHz. With these devices, linear tuning of frequency with bias voltage case can be achieved for VCOs with wide tuning bands using transistors. Gunn or IMPATTs as well as with tunable filter and amplifiers. These diodes are an excellent choice for modulator applications where better linearity or nearly constant modulation sensitivity is desired.

Notes: 1. All GaAs tuning varactors are available as standard in the ODS 30 package. Alternative package styles including chip form are available on request. When ordering, specify the desired case style by adding the case designation as a suffix to the type number. 2. Case parasitics (C P and L S ) are given in the case styles section. The CP values listed typically have tolerances of ±0.02 pF. 3. The nominal tolerance at -4 Volts is ±10%. Closer tolerances are available upon request. By adding the suffix A to the part number, a tolerance of ±5% can be obtained. 4. Gamma is within the limits of 0.90
