MADCSM0012

www.DataSheet4U.com PCS LNA/Downconverter 1800-2000 MHz Features Highly Integrated LNA and Downconverter 3mm 16-Lead PQFN Operates over 2.7 V to 5 V Supply Voltage Low Noise Figure: 2.3 dB Typical High Input Intercept Point: -9 dBm Typical Continuous Current Control Downconverter Low LO Drive Level: -10 dBm MADCSM0012 V2 Functional Block Diagram Description M/A-COM’s MADCSM0012 integrated downconverter combines a low noise amplifier, a RF amplifier, a downconverting mixer, an IF amplifier, and LO buffer amplifier. The MADCSM0012 is packaged in a low cost 3mm 16-Lead PQFN with an exposed pad for improved high frequency grounding. M/A-COM designed the MADCSM0012 for handsets requiring wide dynamic range and low power consumption. By application of a suitable control voltage to pin 6, the linearity of the device can be controlled in real time to keep the current as low as possible The MADCSM0012 is fabricated using M/A-COM’s 0.5-micron low noise E/D GaAs MESFET process. The process features full passivation for increased performance and reliability.
