HMC173MS8
GaAs MMIC VOLTAGE-VARIABLE
ATTENUATOR, 0.8 - 2.0 GHz
Features
Single Positive Voltage Control: 0 to +3V
High Attenuation Range: >50 dB @ 0.9 GHz
High P1dB Compression Point: +16 dBm
Ultra Small Package: MSOP
General Description
The HMC173MS8 is an absorptive voltage vari-
able attenuator in an 8-lead MSOP package. The
device operates with a positive supply voltage and a
positive control voltage. Unique features include a
high dynamic attenuation range and excellent power
handling performance through all attenuation states.
The HMC173MS8 is ideal for operation in wireless
applications between 0.8 GHz and 1.6 GHz. 1.7 to
2.0 GHz operation is possible, with a reduced maxi-
mum attenuation of 30 dB and increased VSWR.
The HMC173MS8 can be used with an external
driver circuit for improved linearity of attenuation.
