These thermal oxide passivated diodes feature high capacitance ratio and quality factor. They are well suited for octavebandwidth tuning in the HF to UHF frequency bands. The standard capacitance tolerance is 10%, with tighter tolerances available. Capacitance matching at one or more bias voltages is also available.These diodes are offered with standard Sn/Pb plating, as well as with 100% matte Sn plating on our RoHS compliant devices. Applications The MA4ST400 series tuning varactors are useful for octave bandwidth tuning applications in the HF through UHF ranges. Applications include VCOs and voltage tuned filters in radios, cable TV tuners and test instruments where low cost and excellent lot-to-lot repeatability are critical. Linear tuning performance is available from 3 to 8 volts. 1 V1 Absolute Maximum Ratings @ TA=+25 C (Unless Otherwise Noted) 1 Parameter Absolute Maximum Reverse Voltage 22V Forward Current 50 mA Total Power Dissipation 250 mW Operating Temperature -55 C to +125 C Storage Temperature -55 C to +125 C 1.
