HMC473MS8E

ATTENUATORS - SMT 5 5 - 156 HMC473MS8 / 473MS8E v01.1105 GaAs MMIC VOLTAGE VARIABLE ATTENUATOR, 0.45 - 2.2 GHz Typical Applications Features The HMC473MS8 / HMC473MS8E is ideal for: RoHS Compliant Product Cellular, UMTS/3G Infrastructure Single Positive Voltage Control: 0 to +3V Portable Wireless High Attenuation Range: 48 dB @ 0.9 GHz GPS LETE Functional Diagram High P1dB Compression Point: +15 dBm Ultra Small Package: MSOP8 Replaces HMC173MS8 General Description The HMC473MS8 & HMC473MS8E are general purpose absorptive voltage variable attenuators in 8-lead MSOP packages. The devices operate with a +3.3V supply voltage and a 0 to +3V control voltage. Unique features include a high dynamic attenuation range of up to 48 dB and excellent power handling performance through all attenuation states. The HMC473MS8 & HMC473MS8E are ideal for operation in wireless applications from 0.45 to 1.6 GHz. Operation from 1.7 to 2.2 GHz is possible with a reduced maximum attenuation of 29 to 32 dB. Improved control voltage linearity vs. attenuation can be achieved with an external driver circuit. O Electrical Specifications, TA = +25° C, Vdd = +3.3 Vdc, 50 Ohm System Parameter Min. Typ.
