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.
