Surface Mount Abrupt Tuning Varactors MA45430 Series V3.00 Features SOT-23 lSurface Mount Package lLow Cost lHigh Quality Factor lTape and Reel Packaging Available lSPC Controlled Process for Superior C-V Repeatability lAvailable as Singles and Common Cathode Pairs Description The MA45430 series are abrupt junction silicon tuning varactors in the SOT-23 surface mount package. These thermal oxide passivated diodes feature high capacitance ratio and quality factor. They are well suited for tuning in the HF to UHF frequency bands. The standard capaci- tance tolerance is ±10%, with tighter tolerances available. Capacitance matching at one or more bias voltages is also available. ConŢgurations TOP VIEW Applications The MA45430 series tuning varactor is useful for tuning applications in the HF through UHF ranges. Applications include VCOs and voltage tuned Ţlters in radios, cable TV tuners and test instruments where low cost and excel- lent lot-to-lot repeatability are critical. Ordering Information The part numbers shown are for single diodes. When (SINGLE) (COMMON CATHODE PAIR) ordering diodes in common cathode pairs add suffix “CK.” For example, MA45436CK speciŢes model number MA45436 as a common cathode pair.
