HMC245AQS16 / 245AQS16E
v00.1213
GaAs MMIC SP3T Non-REFLECTIVE
SWITCH, DC - 3.5 GHz
General Description
Features
Functional Diagram
The HMC245AQS16 & HMC245AQS16E are low cost
non-reective SP3T switches in 16-lead QSOP sur-
face mount packages. Covering DC to 3.5 GHz, the
switch offers 30 to 40 dB isolation and a low inser-
tion loss of 0.7 dB. A 2:3 TTL/CMOS compatible
decoder is integrated on the switch requiring only 2
control lines and a single +5V bias to select each path,
replacing 6 control lines normally required by GaAs
SP3T switches.
Low Insertion Loss: 0.7 dB @ 2.0 GHz
