The LO drive for the MD57-0001 can range from -5 to +5 dBm without severly impacting the mixer’s performance. The MD57-0001 is ideally suited for cellular band communications handsets’ that can provide only minimal amounts of LO drive. Typical applications include frequency up/down conversion and IQ modulation and demodulation in digital receivers and transmitters. +.008 .063 -.004 1,60 +0.20 -0.10 16XY PIN # 1 .002 ±.002 0,05 ±0,05 .031+.004 -.007 0,79 +0.10 -0.18 The MD57-0001 utilizes a patented “floating-FET” architecture. The on-chip LO amplifier allows the MD57-0001 to operate with as little as -5 dBm of LO drive making it an ideal choice for low power portable designs. The MD57-0001 is fabricated using M/A-COM’s 0.5 micron low noise GaAs MESFET process. This process features full passivation for increased performance and reliability. The MD57-0001 is 100% RF tested to ensure superior performance specification compliance. .110 ±.008 2,80 ±0,2 +.004 -.002 +0.10 0,40 -0.05 .016 +.008 .043 -.004 +0.20 1,10 -0.10 +.004 .006 -.002 +0.10 0,15 -0.05 .008 MIN 0,20 MIN Ordering Information Part Number MD57-0001 MD57-0001TR MD57-0001SMB Package SOT-26, 6-Lead Plastic Package Forward Tape and Reel* Designer’s Kit *If a specific reel size is required, consult factory for part number.
