GaAs MMIC VOLTAGE VARIABLE ATTENUATOR 800-2000 MHz
FEBRUARY 2001
Features
General Description
SINGLE POSITIVE VOLTAGE CONTROL: 0 to +3V
HIGH ATTENUATION RANGE: >50 dB @ 0.9 GHz
The HMC173MS8 is a miniature absorp-
tive voltage variable attenuator in an 8-
lead MSOP package. The device oper-
2 ^{HIGH P1dB COMPRESSION POINT: +16 dBm}
ates with a positive supply voltage, and a
positive control voltage. Unique features
ULTRA SMALL PACKAGE: MSOP
include a high dynamic attenuation range,
and excellent power handling performance
through all attenuation states. The
HMC173MS8 is ideal for operation in wire-
less applications between 800 MHz and
1600 MHz. 1.7 to 2.0 GHz operation is
possible, with a reduced maximum attenu-
ation of 30 dB and increased VSWR. The
HMC173MS8 can be used with an exter-
nal driver circuit for improved linearity of
attenuation.
