SWITCH, DC - 2.0 GHz
Typical Applications
The HMC183QS24 is ideal for:
• Basestation Infrastructure
Features
Low Insertion Loss (1 GHz): 0.8dB
Integrated 3:8 Decoder
24 Lead QSOP Package
General Description
Functional Diagram
The HMC183QS24 is a low-cost non-reflective
SP8T switch in a 24-lead QSOP package for use
in antenna diversity, switched filter banks, gain/
attenuation selection, and general channel mul-
tiplexing 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 pack-
age occupies the same area as a 14-lead SOIC.
See positive bias/TTL version HMC253QS24.
