Description
M/A-COM’s MD59-0021 is a fully integrated downconverter IC with LNA, RF amplifier, downconverting mixer, IF amplifier and LO buffer amplifier in a miniature TSSOP-16 plastic package with exposed metal lead frame backside for improved high frequency grounding. The MD59-0021 is ideally suited for CDMA handset applications where wide dynamic range and low power consumption are important receiver requirements. The MD59-0021 is fabricated using a M/A-COM’s 0.5 micron low noise E/D GaAs MESFET process. The process features full passivation for increased performance and reliability.
