24 Lead QSOP Package
General Description
The HMC183QS24 & HMC183QS24E are low-cost
non-reflective SP8T switches in 24-lead QSOP pack-
ages for use in antenna diversity, switched filter
banks, gain/attenuation selection, and general chan-
nel multiplexing applications. A 3:8 decoder is inte-
grated on the switch, requiring only 3 control lines with
a negative bias to select an RF path. The 3:8 decoder
replaces 16 control lines normally required by GaAs
SP8T switches. Switch outputs are terminated when
“off”. The QSOP24 package occupies the same area
as a 14-lead SOIC. See positive bias/TTL version
HMC253QS24.
