HMC473MS8 / 473MS8E v01.1105 GaAs MMIC VOLTAGE VARIABLE ATTENUATOR, 0.45 - 2.2 GHz ATTENUATORS - SMT 5 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 High P1dB Compression Point: +15 dBm TE Ultra Small Package: MSOP8 Replaces HMC173MS8 Functional Diagram General Description SO LE 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.

A breakpoint linearization circuit will scale the voltage supplied to the control line of the HMC473MS8 & HMC473MS8E, so that a more linear attenuation vs. control voltage slope can be achieved. A -3.3V and +3.3V supply is required. TE Diode and resistor values which define the op-amp gain, and breakpoint were selected to optimize a measured production lot of attenuators at 0.9 GHz. R7 may be varied to optimize the performance of any given attenuator. If the input voltage to the linearizing circuit will not drop below 1.0V, the R9 and D2 may be omitted, and this will greatly reduce the overall power consumption of the driver circuit. The linearizing circuit has been optimized for 0.9 GHz attenuation applications. A similar approach may be used at other frequencies by adjusting R1 - R9 resistor values.
