This series of varactors is designed for high capacitance ratio and low voltage operation. Each varactor type has a better than 3:1 capacitance ratio between 0.5V and 3.0V. 1. Operation of this device above any one of these parameters may cause permanent damage. 2. Please refer to application note M538 for surface mounting instructions Applications The MA4ST300 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 to cover wireless application bands up to the 2.4 GHz WLAN band. Applications include VCOs and voltage tuned filters. 320 330 340 350 Active Pagers CT2 SMR PDC GSM IS-136/95 NMT JCT NMT TACS AMPS PCS GPS DCS1800 PHP DECT WLAN RoHs Compliant parts 0.25 Part Number RoHs Compliant Part Number 0.5 0.75 1.0 2.0 3.0 FREQUENCY (GHz) MA4ST320 MA4ST330 MA4ST340 MA4ST350 MAVR-000320 MAVR-000330 MAVR-000340 MAVR-000350 Fig. 1 Typical Device Selection by Frequency 1 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.

Also Offering RoHs Compliant Equivalent Parts Low-Voltage / Wide Band Si Hyperabrupt Varactors Mounting Information The illustration indicates the recommended mounting pad configuration for the SC-79, SOT-323 and SOD-323 packages. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices.
