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 0.25 1 MA4ST320 MAVR-000320 MA4ST330 MAVR-000330 MA4ST340 MAVR-000340 MA4ST350 MAVR-000350 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
