| MA45400 Series Si Abrupt Tuning Varactor Diode Rev. V4 Features * Surface Mount Plastic Packages : SOT-23 * SPC Process for Superior C vs V and Q vs V Repeatability * Lead-Free (RoHs Compliant) equivalents available with 260C reflow compatibility SOT-23 Description M/A-COM's MA45400 series is a highly repeatable, UHCVD/ion-implanted, abrupt silicon tuning varactor in a cost effective surface mount package. This series of varactors is designed for general purpose tuning in the HF to UHF frequency bands. It is efficient for wide tuning across a 0-30V range. These diodes are offered with standard Sn/Pb plating , as well as 100% matte Sn plating on our RoHs compliant equivalent devices. Absolute Maximum Ratings 1,2 @ TA=+25 C (Unless Otherwise Noted) Parameter Reverse Voltage Forward Current Operating Temperature Storage Temperature Absolute Maximum 30 V 50 mA -55 C to +125 C -55 C to +125 C Application M/A-COM's MA45400 series tuning varactor is useful for tuning applications in the HF through UHF ranges. Applications include VCO's and voltage tuned filters in radios, cable TV tuners and test instruments where low cost and excellent lot to lot repeatability are critical.
