HMC473MS8 Voltage Variable Attenuator SMT, 0.45 - 2.2 GHz
The HMC473MS8(E) is a general purpose absorptive voltage variable attenuator in an 8-lead MSOP package. 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(E) is 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.
