SWITCH, DC - 3.5 GHz
Features
High Isolation: >45 dB
Positive control: 0/+5V
Non-Reflective Design
Ultra Small Pakcage: MSOP8G
General Description
The HMC284MS8G is a low-cost SPDT switch in an
8-lead grounded base MSOP package. The design
has been optimized to provide high isolation with
minimal insertion loss for medium and low power
applications. On-chip circuitry allows positive volt-
age control operation at very low DC currents with
control inputs compatible with CMOS and most TTL
logic families. In the “OFF” state, RF1 and RF2 are
non-reflective. See reflective high isolation SPDT
version, HMC194MS8.
