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 d B Typical High Input Intercept Point: -9 d Bm Typical Continuous Current Control Downconverter Low LO Drive Level: -10 d Bm MADCSM0012 V2 Functional Block Diagram Description M/A-’s MADCSM0012 integrated downconverter bines 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- 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-’s 0.5-micron low noise E/D Ga As MESFET process. The process features full passivation for increased performance and reliability.
