SPECIFICATIONS
Insertion loss; Max. 0.3dB
Isolation; Min. 20dB (Between open
contacts)
Min. 30dB (Between contact
sets)
V.S.W.R.; Max. 1.2
2. Surface mount terminal
This relay is a surface-mounted model
with excellent high-frequency proper-
ties. In addition, it can use a microstrip
line in the base circuit design which
spares the labor of machining the base.
