It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The AM50-0006 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AM50-0006 can operate from any positive supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 3 mA to 20 mA with an external resistor. The AM50-0006 is ideally suited for use where low noise figure, high gain, high dynamic range, and low power consumption are required. Typical applications include receiver front ends in PDC1500, DCS-1800, DCS-1900, PHS and other PCN/PCS applications. It is also useful as a gain block, buffer, driver and IF amplifier in both fixed and portable PDC, PHS, and PCN/PCS systems. The AM50-0006 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability. The AM50-0006 is 100% RF tested to ensure performance specification compliance. .031 +.004 -.007 0,79 +0.10 -0.18 .016 +.004 -.002 Ordering Information Electrical Specifications : TA=+25C, Z0 = 50 , PIN = - 30 dBm 1 Parameter Test Conditions Gain Noise Figure Input VSWR Output VSWR w w V DD = 3 Volts .D w t a S a Units dB dB e h Min. 15 Part Number AM50-0006 t e U 4 0,40 +0.10 -0.05 .c .002 .002 0,05 0,05 +.004 .006 -.002 +0.10 0,15 -0.05 m o Package +.008 .043 -.004 1,10+0.20 -0.10 .008 MIN 0,20 MIN SOT-26 Plastic Package Forward Tape and Reel* 1400-1520 MHz Designers Kit 1700-2000 MHz Designers Kit AM50-0006TR AM50-0006PDC AM50-0006PCS * If specific reel size is required, consult factory for part number assignment. 1500 MHz Typ. 18 1.60 2.2:1 1.5:1 Max. 20 2.00 Min. 15 1900 MHz Typ. 17.5 1.65 1.5:1 1.5:1 0 -6.0 35 10 4.5 6.5 10 Max. 20 2.00 V DD = 3 Volts Output 1 dB Compression Input IP3 Reverse Isolation V DD = 3 Volts V DD = 3 Volts dBm dBm dB 1 -5.0 35 6.5 Drain current V DD = 3 Volts mA 4.5 1.
