1. High frequency characteristics

(Impedance 50

Ω, ~1.0GHz)

• 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.
