MADCSM0011

www.DataSheet4U.com Dual Mode Cellular Downconverter 869 - 893 MHz Features Dual Mode Downconverter with LO Amplifier 3mm 12-Lead PQFN Package Operates over 2.7 V to 5 V Supply Voltage High Gain: 12.5 dB Typical High Input Intercept Point: +8 dBm Typical Low Current Draw: 12 mA Typical Adjustable IP3 Level Low LO Drive Level: -10 dBm MADCSM0011 V2 Functional Block Diagram ` ` ` Description M/A-COM’s MADCSM0011 integrated downconverter combines a downconverting mixer, an IF amplifier, a LO buffer amplifier and an output mode switch. The MADCSM0011 is packaged in a low cost 3mm 12-Lead PQFN package with an exposed pad for improved high frequency grounding. M/A-COM designed the MADCSM0011 for handsets requiring wide dynamic range and low power consumption. A mode switch is incorporated into the MADCSM0011 to switch between CDMA and AMPs operation. The MADCSM0011 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. ` ` ` Pin Configuration Pin No. Pin Name 1 2 3 4 5 6 MIX GND LO IN GND LOA VDD IFA SRC CDMA IF OUT GND AMPS IF OUT MODE SEL IFA VDD IFA IN Description Mixer RF Input/Mixer IF Output DC and RF Ground Local oscillator input (-10 to -5 dBm) DC and RF Ground LOA supply voltage; RF bypassing required Parallel RC network determines the IFA Current, Gain and IIP3 CDMA IF Output of downconverter; IF matching required DC and RF Ground AMPs IF Output ...
