Product Detail

MACOM’s MA4ST200 series is a ion-implanted, hyperabrupt junction, silicon tuning varactors in SOT-23, SC70 3LD, and SOD- 323 surface mount packages. This series of varactors is designed for high Q and low voltage operation. Each varactor type has a Q greater than 400 at -2 V. These diodes are offered with standard Sn/Pb plating , as well as 100% matte Sn plating on our RoHS compliant equivalent devices. The MA4ST200 series tuning varactors are useful for wide band tuning and low phase noise applications where the supply voltage is limited to 5 volts or less. These varactors have been specifically designed for use in the wireless communications up to the 2.4 GHz band. Applications include VCOs and voltage tuned filters.
