Features
SINGLE POSITIVE VOLTAGE CONTROL: 0 to +2.5V
HIGH ATTENUATION RANGE: >50 dB @ 1.9 GHz
HIGH INPUT IP3: +15 dBm Typical
(All Attenuation States)
ULTRA SMALL PACKAGE: MSOP
General Description
The HMC210MS8 is a miniature absorptive voltage variable attenuator in an 8lead MSOP package. The device operates with a positive supply voltage (+2.5V),
and a positive control voltage. A unique
feature is the high third order intercept
point for all attenuation states. The
HMC210MS8 is ideal for operation in PCS
applications at 1.9 GHz and W-CDMA
applications through 2.2 GHz. Operation
up to 2.3 GHz is possible, with a reduced
attenuation range of 31 dB.

Note 1:Ri se T ime(tRise) and Fall Time (tFall) are measured between the 10% and 90% attenuation values.
Note 2:The On Time (tOn Total)is defined as the time fromthe 50% control signal level point to the maximum attenuation
level.
