General Description
DC - 8.0 GHz
4x4 mm SMT Package
The HMC321LP4 & HMC321LP4E are broadband non-
reflective GaAs MESFET SP8T switches in low cost
leadless surface mount packages. Covering DC to
8 GHz, this switch offers high isolation and low inser-
tion loss. This switch also includes an on board binary
decoder circuit which reduces the required logic con-
trol lines to three. The switch operates using a positive
control voltage of 0/+5 volts, and requires a fixed bias
of +5v. This switch is suitable for usage in 50-Ohm or
75-Ohm systems.
* DC blocking capacitors are required at ports RFC and
RF1, 2, 3, 4, 5, 6, 7, 8. Their value will determine the lowest
transmission frequency.
