Functional Diagram

General Description

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.
